Panic, if we have a bone stock Chevy 235 inline-6:
What, in your opinion, is the best carburetor (of any carburetors ever made) and intake manifold combination for that engine? Assume normal everyday truck driving.

Suppose you are given a Sprint QJ, a AFB 9400s and a "390" (sorry, no picture):
1.) For the above engine, which one would work the best? "390", QJ, AFB or none?
2.) Which intake manifold would work the best?
3.) For the carburetor selected in 1) above, what could be done to optimize the carburetor to run best on that engine?

"Adding CFM to a truck will only help at engine speeds you don't want to use."
"I found there was nothing to gain beyond 400 CFM."
