So I have a 1975 f100 supercab, don't hate me, but it has a 355 small block Chevy with a turbo 400 trans. The engine is built pretty good since it came out of a dragster camaro. So the problem is while I'm driving down the road the engine will randomly shut off on me even though I warm it up to operating temps, is it the fuel pump going out or the carb needs an adjustment? I'm really lost so if anyone can please help me out its killing me I just wanna be worry free while driving again!
It seems like all my Chevy friends have brand new fuel pumps because they randomly just quit. sometimes they start working again, sometimes they pull the spare out from under the seat and keep going. I have no idea what causes it but I'm sure they're not buying piles of defective pumps. I don't know if that helps you but an electric pump was one of their fixes

Oh really?? Thanks for the info I'll look deeper into it!
Does the truck immediately re-fire after it stalls or do you ahve to wait for a period of time?
Yeah it refires right after it shuts off, it doesn't like back fire or anything just shuts off with out a warning, I have installed a fuel pressure gauge and it was running about 9 psi so I installed a fuel pressure regulator and I set it to about 6 psi So it doesn't wear out the carb
I.E....wires from dizzy or coil to ign switch. I had a weird one like you describe...found my tach lead had rubbed a spot in the wire covering causing an occasional short. In my youth I had run the lead down along the steering column and through the firewall there...over the years the column would deflect enough when turning to slowly wear the cover and cause the issue...only when turning right becuase the wire was on the left side of the column where it went through the firewall.
