Try a slightly richer primary cruise calibration.
(smaller lean step on the metering rod, or just a larger pri main jet.)
a richer primary helps throttle response.
Make sure the pcv is connected to the back of the carb. not to the front.
no vacuum leaks. Brake booster etc
May need a larger accelerator shooter. ( drill out +.003" or edelbrock
service part shooter kit)
A afr gauge helps you dial it in.
carb spacers sometimes create throttle response issues.
trans torque converter stall speed is critical.
a stock converter won;t work very well.
3000 stall minimum....3500 stall is not too much for that cam.
When does it bog-hesitate? rolling into the throttle from cruise,,, or when you rug it hard?
rug it from idle.....
rug it from steady cruise.....
rug it from hiway cruise.....
Pcv is hooked to the front brake booster is in the back. Why does it matter which one? I have a 2800-3000 stall converter. It hesitate when punching it from a dead stop. Its fine rolling into out.
