anyone have any experience with dh-racing? they have an intake manifold/throttle body combo that is guaranteed to make 25 at the wheels.........its a stock intake manifold fully ported w/ a 74/67 taper bored throttle body. this runs ya 550 i cant decide between this and an eddlebrock victory-x manifold w/ an eriks racing 70mm throttle body. this runs ya about 700 which do you think would give the best gains and at the same time reliability for my money? help will be appreciated!!
