FAST 102 on a 5.3? Has anyone run a Fast 102 intake on a 5.3? I have the chance to pick one up locally and wonder if I would be gaining or losing over the LS2 intake on my setup. Combo listed below.
2007 LH6 5.3L 243 heads stage 2.5 porting by PRC, chambers milled to 58cc. Pat G spec EPS 222/224 .604/.604 on 112+1. 1 3/4" lontubes into 2.5" duals, Yank SS3600 converter. Ported and Polished truck DBW 87mm TB.
The real appeal is the price, it's local and I can use my LS2 fuel rail and injectors.

No way in heck will you be losing power over an LS2, even on a small 5.3.
You have a decent cam and well flowing heads, so the FAST is only going to help especially up top. Off idle you might lose some torque, but you don't have to worry about that with a 3600 stall.
