Ported LS6 Intake vs. Ported FAST 78mm Intake I've tried the search for a couple of days and it keeps screwing up. So, I was just curious if the FAST 78mm intake was worth almost double for what the LS6 can be bought for. Here is the motor set-up:
-383 LS1
-Patriot Stage 2 5.3 Heads
-F13(230/232-.595/.585-114+4)
It'll be going in my truck with a 2600 stall and 3.90 gears. Which one do ya'll think would be the best bang for the buck?

The intake plenium on the 78mm FAST combined with a 3mm larger TB means it will offer more potential than the LS6 intake. Espcially on a larger displacement motor and one using the higher rpms as most aftermarket cams require.
If you already have a Ls6 intake TPIS will convert it to a 90mm manifold, you'll need a new TB but you'll probably be on par or slightly exceed the FAST 78 on the correct setup.
Personally I'd either stick Ls6 and ported stock TB as the budget option, or if I was going to spend the money go FAST 90 and PTM/NW 90mm TB.

ls6 has great power so ive heard and for the price i think it is a great mod to do but if you've got $1100 laying around do the fast 90/90 combo. or just do the $325 ls6 and then port your own TB just my .02
