How much power do you want to make??..my 416 made 520 h.p. 500 tq..using a Edelbrock Air Gap,if you go the single plane route i'd use a victor 340..whatever you do DON'T waste your money on those chinese ripoff professional products intakes.anyone i know has had issues with them..as for that photo in a previous reply thats exately what a professionals intake looked like when Vic Edelbrock himself showed it on a program i was watching,gasket mismatch was just one of the issues,in fact there are a few guys here that after buying the "chinese" junk,went out and bought an Edelbrock and saw better performance from their motors..
