maybe this graph will help, this is when i had swapped intakes, the l92 truck intake to the F.A.S.T LSXr car style intake, if you look at the graph where the torque comes in quick or at lower rpms thats the truck intake, the further the torque is in the rpm range thats with the FAST intake..
i wont go into big detail as im just giving you an idea as our cams were pretty close mine being a 232/238 609/612 advertised duration was 230/236.. once again just giving you an idea.
by the way thats in a 6.0 ;)
