i just rebuilt my 79 chevy 350 and it is lacking quite a bit of power. It is a 350 bored .030" over new comp cam .475 intake lift, hydraulic lifters and double roller timing chain , hypereutectic pistons edelbrock intake, edelbrock 650 carb, hei super coil distributor, headers, ect. It is lacking power, always smells like it is running rich and is sometimes hard to start(have to hold gas to the floor). The plugs have good color. I have adjusted the valves/ rockers, not it. I have played with the timing, not it. I put a new distributor and wires on, not it. i tried messing with the carb settings and the more you lean it out the less it likes to run and the no matter how rich you make it run it doesnt gain power. I put a new carb on it, no difference. The only thing i can think of is that the cam is not degreed right but the two marks on the cam gears were lined up when assembled and the lifters appeared to be in correct timing with the strokes. I would appreciate and thoughts or help.

thanks
