Here is the Info
75 400 SBC bored 40 over( Just bought afer rebuild)
750 CFm Carter AFB Carb ( Professionally rebuilt, and tested)
Polished Stock Heads
Med cam (Owner of Engine lost cam specs)
th400 trans (Convertor is unknown(assume Stock))
new Stock Mechanical Fuel Pump, with Regulator installed and set to 5 PSI
Have the Timing set at 10 BTDC with vac advanced disconnected,
Everything new and working properly Under distrubitor, Accel Hei, and Accel Rotor.
Dual exhaust with long tube headers, through 2 1/4 glasspacks and tail pipe
Hope this is enough.
Now my Question,
I was having an issue with carb (old one was a edelbrock 1405 ) replaced with Carter 750, after adjusting the carb truck cranks and idles good, but when I drop into reverse or park it drops idle to almost nothing then dies, unless feathering throttle. I addjusted the air screw and idle mixture, no change. I have checked for Vac leaks no that i can see or tell. good vacuum at idle in park (around 12 1/2 to 13 steady). Choking doesn't help either.
I am getting dizzy trying to figure this out anyhelp would be appreciated.
Thanks
Chris
