Okay...here goes and hopefully I am describing this right. New GM crate motor (350)will not run at TDC. So I have done this many times before without an issue and it is stumping a couple of other people other than me. The motor was running, just poorly the Dizzy was put in (two teeth off) which I have heard from some people that it makes a difference, and other people said it doesnt. Either way it ran there but not as well as a new motor should. So I decided to pull it and restab it and dial it in. I put it back in at TDC and couldnt get it to start, checked everything that would cause it not to start spark fuel etc.. everything was right. Called a buddy over who busted my nuts about not being able to time a car, and he did the exact thing as me and could not get it started. Long story short it is currently at a buddy of mines shop and he has been going through it without much luck. He can get it to run with the cap two off(crappy) but it will not run where it is supposed to. Checked the timing chain nothing is off, checked the valves, they are moving as they should no cam lobes wiped or anything. Am I missing something stupid? It has a points dizzy now. I was going to go HEI but it doesn not fit. The dizzy is out of a chevy 283 but I dont think that matters. Any help would be appreciated.
