First off, I have a 1959 Chevy 283 that was rebuilt stock last year. It was a 2 barrel engine. After the rebuild i put a weiand street warrior intake with a edelbrock 600 4 barrel, 262 Comp extreme energy cam. The problem is that it runs fine, starting, idling, but when you put in gear it drains the motor down. And its weak. Do i need a stall? Or timing issues, carb adjustments? Or is it the stock heads? ANY HELP?::confused:
The main problem here is that you don't understand matching the cam timing to the static compression ratio of the motor. A camshaft is not a stand-alone part. It is dependent on other facets of the build to get to a well-coordinated platform. I would be very surprised if that motor is even 8.5:1 static compression ratio and common sense would tell me that it's even less than that. Take a look at this chart I put together. Everything on this page was taken directly from the Crane Cams catalog, as far as matching static compression ratio to the 0.050" tappet lift duration.

I have an idea that if you had chosen a cam something like this.....
Crane Cams 114112 2020 Hydraulic Flat Tappet Camshaft Lifter Kit Chevy 262-400 V8 57-87 RPM Range: 800-4400, Duration @.050": 194/204, Lift: 0.401/
that you wouldn't be writing the post here in the first place.

Thanks AutoGear and BuzzLOL, you guys nailed the problem before I chimed in.

Im not sure on most of these questions. I have very little knowledge on engines. Someone rebuilt as stock with a 2 barrel. While still fresh, i had someone install cam and intake. Its just flat running. And as before it loses alot of power when put in gear. Torque converter issue? And the heads are stock. Im not sure which way to turn. Could be simple or expensive....
Remove hot rod cam. Install stock cam. Done.

I agree with some of the info here. Definitely check for vacuum leaks, get the timing right, valve adjustment, etc.
But a 262, [email protected] .050" needs 10-11:1? Really? Even if it's 8.5 I would think it should run ok. Do you think a 262 is THAT big of a cam, even in a 283? Maybe 10:1 would be ideal, tho. (would that mean a 280 Magnum cam needs 12-13:1 then?) Or are you saying smaller motors need to have higher CR than larger motors with the same cam?
Maybe this will help......

I'll check er out, thanks. Just seems to be a fair amount of contradiction on builds sometimes. A 274xe is fine with 9:1 (((didn't say ideal))) but hearing a 262xe needs 10+ just makes me wonder. I do know that a smaller motor needs more static CR to keep up the dynamic CR vs a larger motor with the same cam.....just don't see it being a huge difference.
Thanks.
If you were building a motor, would you want it to be correct or would almost correct be good enough?
