James an intake manifold and header setup that will show dollar to hp ratio gains that significantly beat what is being offered now will be worth every penny and I'll be on the top of the list for buyers!
It seems some are really finding that there is a great restriction in the intake manifold, open it up and optimize it and the makers will probably sell quick but if it doesn't show much of a difference from what some are already doing for practically free besides there own time than the seller will probably start to see cob webs growing in and around there newly designed manifolds, "We would hate to make a bad name witht the aftermarket guru's!"
Oh by the way I am refering to SVT's!!!
