Fast 102 or LS3 Intake on 434ci Stroker Ok,
Trying to decide what intake to go with for my stroker. The Fast 102 or the LS3 intake on the car now. Would love to save the money and run the stocker but if its gonna totally kill me power wise ill go to the FAST. car is a LS3 dry sleeved 4.155 bore 4 inch stroke making 434ci. 237/247 cam on a 114. TEA Stage 2 LS3 heads.

IMHO, I would get the LS3 intake ported by Vengeance or Bare Essentials Racing. Here is a link from Katech that performed an independent test between a FAST 102 and ported LS3 intake.

I'm running my LS7 427 with very similar TEA tweaked LS3 heads and ported LS3 intake w/ a mild 235/239 and 3.90 rearend and made 530/513 on the first dyno during break in. Vengeance will be tweaking for a little more next week w/ new cutouts and EWP. I should be in mid-50s after the tune.
