Have the stock L69 out currently. It was leaking oil and fuel pretty profusely everywhere. Resealing and cleansing the grease ball basically. Was thinking about putting in back in with a set of aluminum heads, a mild roller cam, and possibly an Edelbrock Performer Airgap intake. Not sure if the last part is worth it. The necessary spreadbore version runs $315 and the factory L69 aluminum piece is probably not any worse than a conventional Performer/RPM. Anyhow, the heads I've been mulling over are something like this:

http://www.summitracing.com/parts/tfs-30310006/overview/

What's got me is that it lists the maximum valve lift at only .540". This seems odd. With a 1.5 rocker, even the stock .404" cam would breach that number. My thinking is this spec is the maximum spec of the what the cam lift can be based on a 1.5 ratio rocker, but it doesn't say. But it seems odd to list it as "max valve lift" when that is a function of cam lift AND rocker ratio. I don't want to buy the wrong thing here.

Also I'd prefer to keep the Q-jet and CCC system. Is it likely to play nice with those heads, a cam of something around a 112 LSA 218 @.050 cam with around .450 to .500 lift, headers and true duals? There's no sense having to buy a new carb, fuel system, ignition system, and an alternative converter clutch lock-up for a 305 build. I could theoretically also burn a new PROM chip if necessary. I have a burner and tuner and have burned some new OBD1 EFI chips. Maybe it'd work on CCC stuff as well. The airgap intake, if purchased, would require EGR deletion anyway to avoid an MIL.

Thanks,
Jesse

I believe you will find that the stock valve lift number,(.404),includes the rocker ratio.
So your new cam with a total lift of .450 - .500 will work fine with the advertised .540 total lift figures.
Most total lift numbers are calculated using the most common rocker arm ratio.
I would suggest that you make certain that the springs are properly matched for whatever cam you do put in.
Mis-matched valve springs can reduce valvetrain longevity.

For intake look T the performer air gap 2601( I think)
It's a air gap for a qjet carb. And heads look to see if you can find some used 113 heads. Or look at the trick flow heads they are the only ones with the small combustion chamber for the 305 motor.

I think throwing on a set of Vortec heads and performer intake, along with a set of headers and cam on/in the 305 is a killer way to get good power at a good bang for the buck. The heads you picked are probably the best out of the box heads you can get new right now for a 305, but pricey.

Those TFS linked flow around 240 CFM @ .500 lift on the intake, which isnít much more than a set of Vortecs that flow somewhere between 219 and 229 CFM on most benches. However, the TFS are aluminum and a lot more versatile in that there is a good bit of material there to port them to achieve a much larger volume and minimal cross-sectional area (as well as adding larger valves) for more flow if you go with a bigger engine later.

As far as cams and CCC go, as with picking any cam, you need to match it to the stall speed of the converter. I tuned on a number of electronic carbed 305HOs with around 15 different cams using the stock 2,000-rpm stall speed (if you've ever had transmission work make sure they didn't use a lesser stall speed converter on the rebuild). The first cam I ran in my SSís 305 was a 216/228-112 Crane. While I got it to run OK/fine with the stock converter (more seat duration than the newer high-rate of rise cams like the VooDoo and Extreme cams), the 212/218-110 Comp Iíd get custom ground (back then) would ET better. In fact, the 205/215-112 High Efficiency Lunati cam I used in a few cars would ET better as well with the stock converter. I had to bump the stall speed to 2400 rpm (not cheap back then,, or now either) on the 216/228-112 to get it to ET fractionally better than the 212/218-110 with the stock converter. You didnít have to mess with the lean and rich stops on the carb to get the 205/215-112 running right either.

The last cam I tuned on in a 305 HO was a 254/262, 210/218, .447/.462 - 111 Comp 4x4. It only had a pocket ported set of stock HO heads and I was very impressed at the throttle response and power. It was easy to dial in the carb as well.

I'd never build a 334 unless it was for a matching numbers type build - and if I did, I would say it was a matching numbers 305 - lol. Mainly because you can typically pick up an old 350 block for under $100 and could have considerably more power building a 383 for about the same money (or less).

For just the cost of those aluminum heads you could be well into a 350 build with Vortec 062 heads and GM's LT4 HOT cam.

Thanks Guy, I'll work on that assumption about the lift spec then. What is there to match on the valve springs besides spring pressure? The listed spec for the springs on this head is:

1.470" O.D. single spring with damper
118 lbs. @ 1.800" installed height
300 lbs. @ 1.280Ē open
360 lbs. per inch rate
.540" maximum lift

There is also slightly higher priced version of the head with a dual springs of some sort:

1.460" O.D. dual spring with damper
125 lbs. @ 1.800" installed height
376 lbs. @ 1.180Ē open
420 lbs. per inch rate
.600" maximum lift

I was thinking about this cam package:

Didn't know they made such a thing for an engine that's already so undersquare. This is all adding up to about $2000 on a 305. I think if I was to spend any more, I'd make the leap to a Blueprint crate 383. I'm already contemplating just going that route instead of hopping up a 200k mile L69.

Thanks, I saw the 2601 is a little cheaper than the 2604 and I could get the head in a same-price 86-earlier version to run it. I'd have to buy a cheap set of perimeter-bolt valve covers though and then the overall cost would be same. Not much difference either way, but I figure centerbolt covers are probably slightly less leak-prone.

Interesting. The converter has kind of been in the back of my mind. I'd like to leave the stocker and the CCC. As mentioned, if I have to change those and spend more money, it seems more prudent to just go another route than the 305.

Would those TFS heads and the Comp 218/224-112, .495/.503 I linked up above jive well with that or do I need to go smaller?

Let me preface my answer on the cam by saying an engine is an air pump. It doesnít know if an increase of air entering it is because of head flow or increase in cam size (duration/lift). That said a cam will not idle or act the same for a given displacement when running different heads. If you run a set of heads with increased low lift flow, it will act similar to a lesser flowing set of heads with a larger cam. The newer designed cams with a high rate of rise like the Extreme and the VooDoo have a shorter/lesser seat duration compared to .050 lift than older designed cams. This delivers less overlap at lower lifts and lets the cam idle like a smaller duration cam (compared to the older designs) while providing near identical mid and upper RPM performance to the older designs.

I say all that because how a cam idles and acts right off idle with a stock set of heads will be different when running a set of heads with an increase in low lift flow. In other words an increase in low lift flow is akin to running a larger cam. That 218/224-112 would be right on the edge of what I would consider potentially problematic for a 305 with stock heads and stock stall speed. With the increased flow from the better heads it more than likely will be a little hard to "tune". If you already understand all the adjustments for the CCC or willing to learn by a little trial and error, then you would probably be OK with that cam and the TFS heads Ė especially if you can change the timing curve to a more aggressive curve in the chip. If not, then youíre probably going to be better off running something a little smaller like this one Ė Lunati High Efficiency Cam 262/270 -112, 211/219, and .507/.515. This would be OK to run on the heads with the .540 lift.

http://www.summitracing.com/parts/lun-20120710/overview/

Stick with the full roller rocker arms. Those you listed are a bit overkill for this set up though. These would be fine for $160 a set

Lots to consider Jesse.
I was just trying to point out one option for the 305.
But,if it were me,I would want something a bit bigger right from the start.
The ATK line of crate engines are a good choice;
http://www.summitracing.com/int/parts/hpe-hp36c/overview/
They have a good reputation and stand behind their work.
You may be better off to save a bit more money and buy something that will give you more "bang for the buck" than sink money into a 305.
Big blocks fit under the hood of a Monte without too much work;

I'm in the same boat with you on the 305 and very interested in what you end up doing with it. I'd be interested to see every kind of power you get. My plan was to use a lunatic voodoo cam but I haven't done anything yet.

I just recently did some upgrades to my 30,000 mile stock 305 in my '86 SS with great results. I went by a 305 build I did a few years ago for another project. I used a Lunati High Efficiency 272 cam (.454" lift, 217/217 duration @ .050", on a 112 LSA). I also used my stock CCC system and stock torque converter. I'm running Hedman Elite full length headers with a X-pipe and custom exhaust. I did a 1228079 ECM swap with a custom ZZ4/L69 chip by member BitFlipper. Stock ignition, but used a Hypertech street/strip coil and Taylor StreeThunder wires. Now, I've been playing more and more with the timing lately and this cam tends to like a lot of it. I have it currently set at 12 degrees initial and it really runs great. If I was rebuilding the entire engine, this setup would be great with a set of flat top pistons and a set of Vortec heads that I've used in the past. Right now the stock heads are at a disadvantage, but the car is a night and day difference from what it was. No engine codes, no adjustments to the carb, and all power accessories work perfect since this cam makes great vacuum. And did I mention it sounds killer with a definite noticeable idle, but yet almost looks completely stock under the hood.

Ok, new question. Is a factory head gasket is ok to use on the aluminum heads? They are still available from GM. Searching around people say the factory gasket compressed thickness is a miniscule .015". I believe that as the ones that come off were some thin steel wafers! The thinnest aftermarket ones I see are these: http://www.summitracing.com/parts/mrg-5780g which have a .028" compressed thickness. Even with the 2cc smaller combustion chambers on the aluminum TFS heads, that would yield a slight decrease in compression ratio from stock. The stock head gasket would bump it up a bit to about 9.8 using those heads if my math is accurate. I'd rather have that number!

I would think the factory gasket could handle the increased cylinder pressure from the increased comp ratio and cylinder filling alright, but I guess I don't know if it can handle sealing the two different metals to each other with their different expansion rates (or even if that Mr Gasket could either for that matter). It'd be sweet to put a nice MLS gasket on, but those are really freaking thick and I'd prefer not to mill brand new heads in order to run them.

Jesse that might be a question for the manufacturer of whatever head you decide to use.
Although if you coated those gaskets with a sealer like this one they might be OK;
http://www.summitracing.com/int/parts/ptx-80697/overview/
And there are other gasket sealers available besides that one.
Also be sure to re-torque the head bolts after the initial break in.
It might also be a good idea to have the block deck's machined to ensure a nice flat surface.

Yeah you can use the stock supersport .015 head gasket on aluminum heads.
GM uses a .015 on the 350 with the 113 heads.

Yeah, I think I'm going to go ahead try the .015 stockers. I guess if they don't hold, I'll mill the heads an run an MLS.

Thanks, everyone.

Here's the current parts list. I downgraded the cam to the XR264R. I also changed the timing chain. The first one I linked says it doesn't work on factory roller blocks. I'm thinking the one I linked is a true roller although it doesn't say so. Looks like a good unit with a Torrington bearing.

I hope all that will work together. Never built a custom engine in my life.

One more question. Cam bearings. I assume I need stock size and not undersize, but there's a lot of choice in brands and metals. I'm not sure what would be the right/best choice here:

Not sure but the heads you have should have the 55-86 bolt pattern so the eddy 2601 intake should be the one you need the 2604 is for the 87-95 bolt pattern.

No I guess I should have looked b4 posting. My bad!

Thread was dead a year and a half ago. It would be nice to get an update on how the build went, don't you think?

Hey Jman093, how did the build turn out?
