Yeah dude,

I am nowhere near the expertise of others on here BUT, as I read your threads you kept talking about no power and thats not right. Before you go tearing down your motor you need to tune what you got cause your motor right now isnt running worth a shit.

I had an old 77 GMC C1500 pickup with a stock 454 low compression smog engine and even though the HP was low, the torque was great and I would roast those tires all day long with a Quadrajet that only opened the primaries and a burt valve in one of the heads. If you want something smooth and very driveable I would get that carb changed and or rebuilt, check your HEI ...maybe full HEI rebuild with new wires and plugs as well. Get a decent timing light and make sure its timed correctly. After all that I cant imagine the motor not smoking the hell out of those tires even with a 3.08 rear end.Do all that and if none works then my guess is real weak cam or maybe installed incorrectly. My guess right now is that carb is in a bad way right now and your HEI is dying for a complete rebuild ( my last small block I couldnt figure out why was so sluggish, turned out the springs in the HEI were rusted and not letting dist adbvance) If that stock motor is fresh, a decent manifold, well tuned carb and adding some headers you should be having traction problems with that car.
