Default Dyno results. Pretty happy.

Finally got my C5 done. Mods include TPS longtubes, catless X-pipe, Borla Axle back, LQ9 shortblock, Stock LS3 heads, Gwatney ported LS3 intake, ported LS2 TB, Pat G 227/236 cam on TSP lobes, and Yank SS3600.

Made 442/412 through the auto on a Dynojet with EEC correction. I’m pretty happy. Thanks to Pat G for the cam spec. I love the torque curve.

That'll put a smile on your face, and require occasional extra shampooing of the pass seat once in awhile.

Solid numbers, i'd recommend a bigger converter for sure if you want the best 1/4 mile out of that set up then when you get the extra cash you got about 20hp sitting on the table ditching the ls3 intake and going to a fast 102

Richy~ good power you have there.

However, the LS3 intake is pretty solid. The LS3 FAST intake is not worth the money in my opinion. I've seen a GPI ported stock/rod mod intake 7 horsepower of a LS3 Fast intake in back to back testing on same exact motor.

I seen dyno results the showed a fast 102 male 19 more HP and 5 more TQ over a ported ls3 so port the fast 102 and the gains will be even better

Np, best way to pick the converter is you want it right where its coming into torque so on your setup if you're going to stay N/A then go with the yank PT converter 4,200 or 4,400

I've seen both Richard Holdener and GPI videos showing dyno results of a ported LS3 intake being within a couple horsepower of the FAST all the way up to 7000 rpm. Then the FAST walked away a little bit. I went the route I did because I'm not revving it past 6800. It is worth more research, but I'm not about to spend $1200 for less than a few HP.
