Default LS6 intake vs. FAST intake on stock LS1

Is there any gains going from an LS6 intake to a FAST intake on a stock LS1?

I say yes, simply because the LS1 heads are pretty good and the LS6 intake is a restriction. Would the gains be substantial, no. If an intake swap is all you plan to do, don't waste your time or money. If heads and cam are in your plans, then it's a smart move.

The difference between the 2 on a stock LS1 isn't worth it IMO. A built LS1 yes...stock no

I wouldn't do it as a first mod. A small cam provides a much bigger gain, followed by heads, headers, and then the FAST.

Cam gains vary based on size, but as long as you have headers, you can see +35 to +75.
Heads are +20 to +55 depending on cost/compression.
Headers generally gain +25 or so.
FAST is generally +15.
Underdrive Pulley +5.

Then how you match them together makes the difference between say 420rwhp or 480rwhp.

That was an excellent answer - thank you so much!

It really helps spending my money on the right stuff
