Well I got it in the car, but I had to use my fuel pump off my other motor which was fairly stock with a mild cam. What I'm concerned about is cylinder no. 1 3 &5 are running at about 560 degrees on the header and the rest all seem to be at about 180 degrees. I checked the plugs and they are all different with #3 seeming to be pretty rich and# 1 still white. I'm getting about 34 degrees of timing at 2500 rpms and I have the idle at about 1100 rpms so it won' t die in gear. I'm also getting some backfiring when I try to accellerate in gear. I'm running 3/8 fuel line. Could maybe the fuel pump is not enough? It is just a stock Chevy pump. I have the idle mixture screws at about 1 1/2 turns out. Max vacuum is at about 15. I checked the headers for leaks and the seem ok. I have the D shaped exhaust ports going into round 1 5/8" headers. Compression is 10to1 on this engine. The carb is a Holley 770cfm that came with it. Seems like a lot on a 350. Any advice is appreciated. I'm really concerned about damaging the engine.
