Yes most defenantly the new Trick Flow. I have read that these are easily the best ones out there now for a SOHC 4.6(even a good bit better than a Bullit) and that they will make quite a different even on a stock motor. Not cheap though as I'm sure their pretty popular right know.
Heres one from Summit but you might find one cheaper on Ebay or somewhere else.
once i get a few things straitened out with my car i will be looking into getting the hardballr intake from texas hot rods. but from the little i know of the trickflow it is a good intake. dont know when you look into getting one but the bbk will be out this fall. it is an individual runner design and the little details that are out about it shows to be a promissing intake also.
