That 108LSA cam will want a good bit of initial base timing.
24 to 26deg 34 to 36 @max advance.

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.....
