So, I'm stepping up the HP from my crate engine this winter and step 1 has been put into motion. Today I picked up the new to me heads, so now it's time to pick a cam to go with them.

Here are my short block specs:

4.00 bore x 3.80 stroke (383 cu), dished pistons about .0030 into the deck, Comp ratio was 9.1:1 with 64 cc iron vortec heads

I picked up a set of GM Fastburn heads that have been upgraded at Brzezinski with Beehive springs and chrome moly retainers. http://www.castheads.com/cylinder-heads/chevy-crate-motors/chevy-604-crate-motor/

These heads have a 62cc combustion camber, 210 cc Intake runner, 2.000 Int/1.550 Exh valves and when used along with a thinner MLS head gasket will increase the compression ratio to 9.6:1.

I have on hand this cam which came in the 604 Crate engine.

Camshaft Part #10185071
Valve Lift: .474” Intake, .510”
Exhaust Duration: 208° lntake, 221° Exhaust @ .050”
Centerline: 112° ATDC Intake, 112° BTDC Exhaust

This is the cam that comes in GM's SP383 which I'm modeling my build after. http://www.chevrolet.com/performance/crate-engines/sp383.html

Camshaft Type (P/N 19210723): Hydraulic roller
Valve Lift (in): .509 intake / .528 exhaust
Camshaft Duration (@.050 in): 222° intake / 230° exhaust
Centerline: 112° ATDC Intake, 112° BTDC Exhaust

The one difference between my build and the SP383 above is I'd like to use my Dual plane intake manifold instead of the single plane high rise manifold that comes on the SP383 and 604 crate. I have one of those intakes as well, so it's possible to use...but I'd like to keep my Qjet and I think the dual plane will fit my needs of low end torque better than the Victor Jr style.

So, any thoughts on cam choice? Most of you know I'm not looking for a high RPM screamer nor drag race engine. I need a rock solid steady performer that will pull between 3000 RPM to 6000 RPM repeatedly and steadily. Performance and reliability are more important to me that a full on peak HP number.

These heads and whichever cam I choose are a huge upgrade from the truck engine cam in my engine now, conservatively a 100 HP/50 ft lbs increase in all the right spots. I'd just like to make only one cam choice and am looking for some help in this matter.

Oh yeah, here's what Santa brought me today...since I know you all like pics...

Lance,after having 2 custom grinds I would not use an off the shelf grind.
You could call Bullet and ask for Tim and get his recommendation.Tim worked for UDHarold and knows cams and Bullet has a bunch of Harold's lobes in their catalog;

Both of my custom cams were UDHarold's design and they both worked awesome !!!

I've thought about going with a custom grind Guy...just trying to see what I have on hand first, then decide if a custom grind will work for my needs.

Digging through GM's crate engine specs has been interesting. I just figured out that the old Fastburn 385 they used to sell used the same cam as the 604 crate that I already have and a dual plane intake manifold, only on a 350 ci shortblock with 9.6:1. It was rated at 385hp,385ft lb. Here is the dyno chart of it.



Basically I have parts on hand to build that exact same top end, but on a 383 cu in short block with the same 9.6:1 compression if I used that 604 crate cam and my dual plane intake. So I know it would work, I just wonder how much more hp and tq it would make (and where in the RPM band) with the extra cubes of the 383?

What I also found out that is good is ALL of these crate engines use the same lifters, same pushrods, same rockers, even the same head gaskets... So I shouldn't have any trouble with valve train geometry reusing all of the other parts I have on hand.

As I understand intake manifolds, the dual plane will help build maximum power lower in the RPM range while the single plane will let more air flow (more power) in the upper RPM range. I really don't plan on spinning this thing higher than 6,000 RPM so the dual plane should work great no matter which cam I choose.

Sound right?

For a car that races from a dead stop and drives on the street I think the dual plane is the way to go.
As far as cam I would look at the Comp Extreme Energy line. If I'm not mistaken those heads are about the same casting as a Vortec just in aluminum?

The Fastburn heads are completely different than the iron vortecs.

Small Block Chevy Cast Iron Vortec Cylinder Head
170cc Intake Ports
64cc Combustion Chambers
1.940'' Int/1.500'' Exh Valves
.475'' Max Lift


Small Block Chevy Fast Burn Aluminum Cylinder Head
210cc Intake Ports
62cc Combustion Chambers
Valves: 2.000'' Intake/1.550'' Exhaust

The Fastburns also have screw in studs...

My buddy runs the xr276hr in his iroc z, 355, vortec heads and stealth ram. Runs 12.50 in the 1/4 and has no shortage of tq down low.

I dont think you would notice much, if any tq loss down low with this cam or another similar to this, but you would definitely Notice the hp.

I would try to get your compression up as high as you can, that will really pick up your tq. If you have plenty of PTV clearance, I would consider milling the heads. If not, running thinner gaskets keeping your quench to .040 will help.

I would also keep the dual plane intake. I really liked my rpm airgap I had on my 383.

Lance, I'd call around to a couple different cam companies and tell them your use and setup and they should give you a couple cams to pick from. That's what I ended up doing with my 355 vortec headed dual plane intake still using CCC system and it's very street friendly with tons of torque from 2000-4500 and I'm limited with the .480 lift. I used a crane XE 262

Lance, what's the maximum recommended lift on your springs in the new heads? That 221/230 cam is going to drop about 4.5" of vacuum over what your running now. Depending on the lift capability I can spec a custom cam that would drop no more than 2" over what you're pulling now and put out more torque and be within a few HP up top.

You might not want to hear this, but those FastBurns are going to drop more low end torque than you'll be able to make up on the top end unless you don't care about the vacuum level.

edit - I'd seriously recommend going with a set of long tube headers to compensate for the low-end drop and for a good bump in midrange torque

My current cam pulls 21" of vacuum at idle, I think I can stand to give a little up. wink I have not seen any maximum recommended lift numbers on these heads, but I'm certain they'll handle any cam I choose to run. The SP383 cam would be the largest lift cam I'd choose at .509/.528. Since they offer it in the crate version with all of the rest of the exact same parts, I'm sure it'll be fine.

I'm not sure why you think the fastburns will drop more low end torque than they'll make up on the top end? Every graph I've seen of engines with them show more torque down low than I have now with my iron vortecs.

I figured it would be you that would bust on me for this! 7 years now and over 15,000 miles on this engine and I'm finally going to bust into it. It has served me well, but the heads with their lift limitations pretty much kept me from making any improvements to it as it was.

Once I decided to concentrate on road courses from here on out, I knew I needed to upgrade the heads...and the rest of the top end at the same time. I still want to keep it "crate engine like" though. I have no desire to get crazy with the cam trying to wring every last little bit out of it. I just want it better...without screwing it up at the same time.

Cam Lift and duration are pretty easy to understand how they let an engine move more air, the lobe separation and intake centerline still befuddles me a bit though.

The guy I bought these parts from suggested I advance his cam 4 degrees... "to really wake that little small block up".

This is where this non-engine builder's eyes start to glaze over and I don't really understand the pros and cons of advancing one certain cam vs another.

By moving the cam 4 degrees advanced you're making the power turn on at a lower engine speed.

Lobe separation angles kind of work in a similar way. By having a larger lobe separation angles with larger duration you're smoothing it out on the low end. Reducing low end power loss and idle chop along with increasing vac.

I'm no cam designer but I have used many in various forms. I would think a newer GM LS hot cam specs would also get you in the area you need to be in too. The only issue with factory cams is the ramp designs as fare as gen 1 SBC go. They have a very limited line up of cams for those engines. With after market they target power under the max lift. The ramp profiles are more aggressive. Giving you more power under the max lift. But these are harder on valve train parts. With what you're doing I would have no worries here.

And all those cams I listed will pull more than the advertised power curves. We ran a 268H in a 69 vette than had a complete engine rebuild. This was a factory 300HP car with 11:1 compression which stayed the same. When it was done it sounded better and pulled harder all the way to 6K with the factory auto trans and no stall.

As Jason said, tighten the quench and make more compression. I would target 10.5:1 - 11:1 with a .038 piston to head distance. It will run fine on 93.

Okay...So here are my HT383 cam specs:

Duration at 050 inch Lift: 196 int./206 exh.
Valve Lift with Factory Rocker Arm Ratio: 0.431 int./0.451 exh.
Lobe Separation (degrees): 109

The cam specs for the cam on my bench (fastburn 385)

Duration at 050 inch Lift: 208 int./221 exh.
Valve Lift with Factory Rocker Arm Ratio: 0.474 int./0.510 exh.
Lobe Separation (degrees): 112

The cam specs for the SP383

Duration at 050 inch Lift: 222 int./230 exh.
Valve Lift with Factory Rocker Arm Ratio: 0.509 int./0.528 exh.
Lobe Separation (degrees): 112

And the XR276

Duration at 050 inch Lift: 224 int./230 exh.
Valve Lift with Factory Rocker Arm Ratio: 0.502 int./0.510 exh.
Lobe Separation (degrees): 110



Looks like to me the XR276 has just a bit less lift, almost the exact same duration but is 2 degrees advanced vs the SP383 cam.

I'm curious just how much difference that would make or if I would even feel it in my application? I'd rather be easier on the valvetrain than try to squeeze every last little bit of juice out of it.

Regarding quench, I'm certain my issue will be how far the piston sits down inside the block at TDC. IMO the best way to combat that would be to deck the block, not mill the heads...and I'm not sure that I desire to take that path...again just to squeeze every last little bit out of it.

I'm a believer in the designers that put the GM crate engines together. My HT383 has held up to some tremendous abuse and performed better than the advertised specs the whole time. Given that no matter what I choose will produce huge gains in HP (and torque) over my current setup, should I really spend a bunch of time and money trying to outthink the GM engineers that designed the SP383?

I'm not doubting anyone here that has chimed in with help, I'm just trying to learn what I can so I can make an informed decision based on my particular needs. I need this engine to last...and I need it to pull hard from 2000 to 6000 RPM repeatedly and consistently with no drama. I am not looking for a peak number on a dyno sheet or a couple more tenths at the drag strip. Does that make sense?

Lance,after having considerable machine work done to my 454 that started life as a GM crate motor I believe that quality machine work is good value for the money spent.
Factory crate motors may be well built but there are inherent manufacturing tolerances that can be improved upon.
Align honing the main journals,decking the block,torque plate honing the cylinders,blueprinting the lifter bores,balancing,etc.,can all contribute to improved power and longevity.

Lance Guy is right 100%.

If you want a strong efficient engine. Buy new ARP main studs, and a windage tray. Align hone it, deck it leaving the piston in the hole .005. Resize the rods with ARP rod bolts too and polish the beams. Buy a set of light weight flat top pistons and use a file fit ring set. Have the block bored over using torque plates. Then you'll have a built proof short block with low leak down numbers.

Yeah...I agree... But I ain't doing all that laugh

I have a set budget I can work with each off season (this is just my hobby ya know) and I have to chose how to spend my available dollars wisely. I also have to take into consideration time constraints (my season starts in April and it has to be installed and sorted out way before then).

The reason this is even a consideration this year is I plan on doing more road course events next year and backing away from trying to win autocross events...so this let me take the money I was going to allocate to rear suspension upgrades and wheels\tires and apply it to horsepower upgrades. My car with it's current suspension and wheels and tires works great on road course corners, it just doesn't handle down the straights as well as it should. With the T56 there is still no reason for me to turn it above 6000 RPM for what I am doing...

With an unlimited budget and desiring the most HP I can wrangle out of the thing, I agree a full blueprinting and machining of everything would be an option...that's just not the case here.

Oh well, I was looking to spend your money so it's easy to say.... laugh

Buy thin head gaskets and let her roll!

sp383 will be a good cam for you just need you compression up to 10 to 10.8 will help lots mill heads or change pistons to flat or dome +12 will do it then you will get hp an tq up in rpm range you want the way chevy made sp383 is to be a everyday driver that acts normal so power should be from 1500-5700 or lil higher

I hear ya on not wanting this upgrade to snowball into a full engine build on a pretty new crate engine. Either that sp383 cam or the xr276 would work well for you, I like the 110 lsa better myself of the xr276. With either cam, getting your compression up will make a big difference. When I built my 383, I had .024" taken off the block to get the pistons at deck height. I'd say check how far they are in the hole and run the correct thickness gasket to get .038"-.040". I would probably mill the heads before tearing the bottom end apart to change pistons.

you dont have to tear bottom apart to change pistons just oil pan unbolt piston push out top of bore put new ones in

One thing to be aware of is "budget" as Lance said. It would be nice to deck the block, align bore, re-ring, new gaskets, balance, on and on. Several years ago we bought a new ZZ4 shortblock, spent $700 just to make it right, decked, several rods need resized, balance was off, this was a brand new shortblock.
At this stage Lance primarily is looking for more top end to keep up with the cars pulling away from him in the straights, not to make fast passes at the drags. A gain of 30 to 50 hp would help. His stockish HT383 did pretty well on the chassis dyno, just ran out of breathe above 5500. Heads and a cam, with the help of the beehive springs will net +6K with the power band move up a good bit.

Those Fastburns along with a good cam is something he will notice in 3rd gear and up. Improving compression to 10.25 -10.50 with good quench would be nice but decking the block to achieve it would be costly in money AND time, race season for him probably starts in late April. Just changing cams in an A/C Monte is a PITA, it would take me a month just to do that.

I kinda like the cam that came with the heads, the specs tell me GM thinks the exhaust side of the head needs a little help, more lift and duration. The 112 separation is good, helps maintain higher idle vac, better brakes assist, smoother idle, more drive-able. Most of the latest high hp LS stuff has much larger separation than 112, and yes the LS head allows you to get away with that. My custom ground Comp roller is 113, idles at 16".

Would be nice if you could find a cam card with all the specs for that cam. Makes it easier to compare apples and apples.
As you already know any cam you buy has to be for the 87 and newer shortblock, roller ready.

Lance the rockers are 1.5? I thought you looked at a set of GM 1.6s. That may make a noticeable gain using the Fastburn cam. I'm sure that has been tried.

The beehive blue springs, you need to know what the specs are. this helps when looking at other cams. Call the place you bought the heads, or drive the Monte over to your local head guy, you need to know what springs ya got.

If you want I'll send you my deck gauge, you'll know exactly how far the piston is in the hole. Add a gasket thickness and you have the quench number. The factory Fastburn gasket is thinner, I think .028, added to the deck height, maybe .028, equals .056, not real good. But, that's the way it is, until the next time.

Spent an hour last night looking for a cartoon. Was hoping to find a 4th gen Monte, huge chromed engine sticking out of the hood, burning rubber out of the garage with a HUGE camshaft sticking out the front of the grille. Caption "they told me to put the biggest cam I could find in it."
Best I could find was a big crankshaft.

Bob, these parts came with 1.5 self aligning rockers, I bought a set of GM 1.6 self aligning roller rockers last year that I've never even looked at. They are still in a box upstairs (I hope).

I dropped the FB heads off at our local speedshop today. He said he'd go over them early next week. He's aware of the work Brzezinski does and knows the parts they use.

For what you're looking to do I would run the cam you bought. It's most likely as good as anything you'll buy unless you're splitting hairs. Advance the cam at the crank plus 4 with a timing set with the advance and retard slots on the crank sprocket.

That thing will pull like a freight train and rev.
