That would solve the symptom but, give it bad street manners in my opinion. I did crank up the idle as an experiment. When put into drive around 950-1000 rpm , there is a loud thump noise, which can't be good for the trans. or diff. When put in Reverse, the thunk is much worse. I'm concerned the reverse band strut will break. The strut was broken when I got the truck. I think the previous owner put it in Reverse while the carb. was on the fast idle cam.
My brother has a car with an almost identical cam in his 340 (8.5:1 compression). Idles just fine. His 340 has a Carter AFB. I wonder what the flow capacity of the front 2 barrels of the AFB are compared to the BBD?
