351w cylinder 4 and 5 dead.
recently built. 351w i did new heads 1.7 rockers long tube headers and it runs nice at least i thought. cylinder 4 and 5 are straight cold headers still painted. firing order is correct 1-3-7-2-6-5-4-8 got a new distributor cap and rotor nope made sure the wires weren’t touching any others didnt make a difference, there is spark at the plug and the distributor and there is also fuel in the cylinders. all plugs and wires are new i swapped the plug with a known good one and nothing i have 150 psi compression on cylinder 5 didnt check 4 yet i ran it for a minute with plugs in and the fuel seemed to not disappear. yet again i checked spark and firing order at the cap again and even went back and re adjusted #5 at tdc compression. injectors are firing spark is sparking and #5 has compression. anyone have an ideas or suggestions?
