while you won't gain TONS you should still make more power.

Sweets10v8 got good results on his stock LS2 engine, granted that was over the crappy LS2 intake.

i was listening to everyone speculate and swear that the FAST was not worth it on anything but a decent sized h/c engine. then i found a lightly ported FAST 90/TB/42# injector package for sale for $1250 shipped.

jumped on it.
ported the manifold a little more at home in 2hrs, never pulling it apart.

then did a-b dyno comparison next to my ls6/ported TB in my moderate CAM ONLY engine.

18hp/12ftlbs peak
5-10hp and torque across the board....NEVER lost power
moved my torque peak DOWN 500rpm
cam peaked at 6400rpm....so its not a high end screamer by any means.

yeah deals are out there you just have to look around. heck i wasn't even looking and found a vengeance ported 92 / 92 big mouth TB for under 1k I didn't think the 102 was worth it yet until results come out and on my baby 346 i can't assume it would take things that much further.

I sold my LS6 intake for $300 and bought a fast 78mm for $300. I ported the whole thing and opened the end up to fit my 85mm ported throttle body. I'm a bang for the buck kinda guy so I coulnd't resist

I sold my old 90/90 setup because it was choking my 415. I did pick up a solid 3 mph and 2 tenths in the 1/8th on my old cam only 346 with the Fast 90/90. This was over my LS6 intake and ported 78mm Throttle body. My best was 7.26@93.5 weighing 3450lbs and running a 28" tall slick and 3.73 gears.
