Why no FAST intake? With a big cube LSx, you'd make more power with an upgraded intake.

Nope...gained 4hp (?) I think it was, but killed the TQ. The FAST intake is better suited to the big port (LS7) heads versus the cnc'd LS3 pieces on our 427...as with our bbc's, bigger (runners) are not always better.

Rob, was the fast intake ported before it was installed? I have seen marginal gains from unported fast setups but ones that have been ported and retuned after the install I have seen huge gains. A local friend of mine with a heads/cam bolt on LS1 trans am picked up 33 rwhp and about 20 ft lbs going from a stock LS6 intake with a ported stock throttle body to a ported fast 92MM intake with matching fast 92MM throttle body.

Is there a victor jr or super victor type intake available now for LS3 heads? I know that these intakes have had pretty good results on LS1s. If they did and it worked well, it would be a much cheaper alternative to a ported fast setup.
