which cam?

[blykins]

I guess I don't understand what your posts or questions are about.

You are posting the specs to a car you've never driven, but the only symptoms you can give are that it won't run on pump gas.

Am I trying to help with the wrong problem?

Woody specializes in Windsors like I do and will tell you the same thing.....something ain't right.

Everything else you have described works as it should. You had a big cam, you put a smaller cam in it, the power dropped a little bit and the torque stayed the same or went up a bit. That's how it always works.

A 950 carb will most of the time make more horsepower on the dyno. Driving them around on the street can be a different story.

I understand that your mechanic didn't build the engine, but if the specs show it's 10.5:1 compression, don't let him or anyone else tell you that 10.5:1 is too high to run on pump gas. If he's telling you that, he's 100% incorrect....COPO Camaro or not.

Someone got something wrong in your engine. Either the heads have been milled too much, the wrong pistons are in it, or the cam is way advanced. Either way, there's no way in the world that I would let someone tell me to quit touching it and drive it like that. Buying drums of race gas gets old quick.
