318 4 bbl and intake upgrade
He said "any 318". I do not disregard the poly 318. The poly 318 is just as much mopar as the LA, was in production for many years, and the LA got many of it's parts from the Poly. I also do not disregard the magnum 318's. Keep in mind, all this because I suggested a 3310 and Dan quoted me say'n "way to much cfm's for a 318". We are talking the 318 C.I. engine. By the way, we are a ways away from the OP's question LOL
