The LSX-DR intake isn't very good......End runner trajectories are terrible & they don't run well upstairs. DR heads aren't very great either.all right guys . i'm looking to build a 454 LSX carb setup on it N.A for my copo camaro i would like to make not less than 850hp so what heads to choose ?? BR7 BRODIX ?? MAST..?? ALLPRO ?? also i would like to fit the LSX-DR intake on it ... what is the best heads choice ??
I made 860 HP (895 HP with inertia) with stock LS7 heads that were re-ported by Greg Good. Intake was an out of the box Holley Hi-Ram.
