I rebuilt the original 351, 5.8 with stock 19# injectors. I also have adjustable fuel regulator. I have a gauge on it and set the pressure at 36#'s. I have a E303 roller cam. I have Eldelbrock performance heads with 202, 1.60 valves.
It will not run with map sensor hooked up. It will run without it, but not very good. The valves are noisy. The are stud mounted. I bought a new stock computer and it still doesn't run right. Have tried 5 map sensors and a new oxygen sensor on exhaust. Nothing changes. Smog pump deleted. This setup ran good on a 392 that I had in in. I turned the timing up too high on the 392
and burned up 2 pistons. That is when I decided to rebuild the 351 with the same parts and it is completely different for some reason. On the 392 I had 30# injectors and a chip burned for them. It worked fine, but when I put in the 351 I removed chip and bought a new computer. I appreciate any assistance ....Thanks, Gene
