Looking for Crane Compu-Cam Camshaft Grind Number CC2040 (Part number 114132) or CC2050 (Part number 114142) for my 305. Thanks.

Back in the mid 80s when I was installing cams in the L69s (at least 10 different cams in fifteen 305 cars), my favorite while keeping the stock stall (around 2000 rpm) was a high efficiency Lunati, 255/265 - 205/215 on a 112 spread. Next favorite was a custom grind (at that time) 252/260 - 206/212 on a 110 spread. The Comp 260/260 - 212/212 on a 110 eventually being about as large as I liked to install.

One of the worst running with the stock converter and a little hard to tune was the 2050 Crane 272/284 - 216/228 on a 112 spread. It was the first cam I installed in my SS with the L69 305 back in 1985. It is really too big for the 305 if you're running a computer carb and stock stall converter. I dropped a good bit of bottom end and netted almost no decrease in ET at the track with the stock converter. I basically traded off a slower 60ft for a little MPH and the ETs were near identical to the stock cam. Now,, from a 35mph kick,, it ran on out quite nicely. However, it wasn't until I put in the 2400 Art Carr stall that the car started working decently at the track. Even with the stall, it wasn't much quicker than an L69 with the stock converter running the 205/215-112 Lunati.

The Summit 288/298 - 214/224 - 112 cam is a popular cam recommended frequently on this site but I installed a couple Alliance 214/224-112 cams (same thing) back in the day. They weren't "bad" but they wouldn't ET as quick with the stock stall as the better idling and more responsive 260/260 - 212/212 - 110 Comp.

The last cam I recommended and tuned on in a L69 was the 254/262 - 210-218 - 111 Comp 4x4. With it's more modern designed lobe profiles, it idled as good and was as crisp as the old high efficiency Lunati I liked so much, but pulled harder than the old 260 (212/212) Comp. I'd highly recommend this one - especially if you're keeping the computer carb and stock stall speed.

Thanks for that information BadSS! So I have the stock 305 that I pulled to reseal. I purchased a set of Edelbrock TES headers and a Edelbrock 3701 intake that I will be bolting in. Basically trying to find cheap HP. That being said and keeping everything else stock, you still think this 4x4 cam you recommended is a good fit? Is the cam a direct fit? Would I need new springs or lifters? Also, roughly how much HP gain would this cam net? Thanks in advance!

Yes, that Extreme 4x4, X4254H, 210/218-111 cam will work “extremely” well with your combination and has a CARB EO number (CA legal). You definitely want to get new lifters for a new cam – using the old ones will more than likely destroy the cam lobes.

IF there isn’t a lot of miles on the springs, they will be OK with the cam. We didn’t replace the springs when we installed this in my friends HO, but it was a low mileage (under 40,000) car. Comp 981-16 springs are good springs that’ll work with the cam and run around $65.

One thing you’ll need to replace if it hasn’t been before is the timing chain. The Cloyes C-3023K at $23 is a good set (it only has a straight up keyway – the cam has 4-degrees advancement already). The 3023X is the same with a 3 keyway sprocket - it’s $2 more but not needed.
Power wise, you’re looking at roughly 15-18 HP from the shorty headers and decent mufflers (no less than dynomax turbos) assuming the catalytic converter is in good shape. The 3701 without blocking the heat risers to reduce some heat (retaining EGR),, but doing a few tricks to the carb (filing the butterfly tang to allow the secondaries to open up more and making sure the linkage is “bent” correctly to allow full opening) should net another 12-15 HP. The cam should add 10 – 13 HP. That may not seem like much, but it is more about shifting and extending the peak RPM and getting more power under the curve than pure HP. If you do all this at one time, it’ll act like a totally different car and I’m sure you’ll be very pleased with the end results.

Sorry to jump in on this conversation but I have an 1987 with 89,000 miles on my 305 and does anyone have any recommendations for a mild idle cam that will wake this engine up a bit? Only mods i might do is different intake and carb.

Not a cam recommendation, but headers wake the L69 up considerably, good luck!!

I created this question what cam are you running on your L69, you can read some of the comments. There are 2 recommendations from other members that have seemed to get them good results.

You can find used ones for sale every so often. A ZZ4 chip like Bitflipper's will help with tuning after a cam swap.
