Overcome with Frustration! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 1973 Chevy c/20 454 has never had the power I think it should, I've replaced plugs, wires, cap, rotor, vacuum advance, centrifugal weights, carburetor kit, vacuum hoses! I've adjusted the valves, timing and carburetor so many times I actually thought I had power and then I drove my friends 1974 c/10 454! His truck is bone stock just like mine but it will roast the tires through intersections! Not saying all I want is to do burnouts, I just want it to run the way it's supposed to run! It's always seems to sound like and run on 7 cylinders but all 8 are firing, I've done compression test with no significant differences throughout all 8 cylinders! I know there can't be much of a difference in horsepower from 1973 to 1974, if any, so what am I doing wrong?
