Been Fighting it since i got the car running. Every time i go to get on it the car will simply cut out and wont pull anything past 3100rpm. Pulls fine till then but after that it hits a wall. I want to make it work and not just toss a 4 barrel on it.
Heres what i have done already,
New ECU
New Dist pick up
New Ballast resistor
Timing at 10 Deg and no vacuum advance total timing at 36
All carbs have been gone through fully
Changed out secondary springs to differnt colors light to heavy springs and still the same
Car Has new valve springs, cam and lifter
14-15 vacuum at idle
63 main jets and stock secondarys.
Idles and free revs great. no hesitiation.
new fuel filter.
Plugs are RN9YC @ .040 gap

Insight would be apprecated to who ever has owned one of these animals.
