I have a 1973 mustang mach 1 with the 302 (originally a 2 barrel) now a edelbrock 4 Barrel. It ran perfectly when I bought it straight out of storage a couple months ago, recently it began to act up when I would drive it in the city, it would heat up to around 200 at stoplights and upon...
500 miles on rebuild, ran fine at 1st
now at 5200 rpm it falls on its face (sounds like hitting rev limeter )
I changed fuel filter , fuel pump,plugs, dissi ,coil, adjusted valves,no change ? could it be computer?
