Ok, well my car need a new magnetic pick inside the distrubitor itself. Your fuel pressure seem to high, try to turn it dow to 45 and see what happens

joey 350 LT4

i dont know how to adjust it lol ill look 2morro, ok so only things left to change are: the pick up in the dizzy fuel injectors and check spark plugs for cracks. everything ignition and fuel wise is new im thinking u were right i got to get the pick up for a msd dizzy is thee drop in one i think tho it might use the same as a stock one tho

joey 350 LT4

ok replaced pick up no changes how ever we moved timing and it got alot better so move it like 1 more degree advanced for like a total of 4 and then it wouldnt idle had to move it back to were i first started to get it to run.... so its gotta be timing and the only thing left is ECU??????? idk any more ............
