umm, idk about, 1400$
a ls6 intake will support up to 450rwhp, with the right combo
i dont think a 346 will really need a 92mm manifold, at least not a dd street car

I could see it gain more on a higher hp car. They base lined this right before they installed the new intake/TB, so the numbers are good.

$1100 seems to be what a 92/92 combo goes for through sponsors. $1400 is on the high end IMO. Detoxx you got a great deal.

That would be awesome for me....I just picked up a Vengeance ported 92 mm combo! I'll be sure to post the dyno numbers once everything is done, however it'll be a little tough to figure out how much of the gain was attributed to the intake and how much was attributed to the heads. Either way, it should be substantial!

From my research, the FAST combo (unported) is typically good for 15 - 20 rwhp over the LS6 intake and the Vengeance port job has been documented to be good for 15+ OVER that. Even if the porting is only worth 5 - 10 rwhp for my stock cube application, it is still well worth it to me.

I have a FAST 92mm that Ron from Vengeance ported out to 95mm and provided a 95 mm tb to finish the combo. At any rate its all sitting in a box until I have money for the SLP 402 that will be replacing my ailing 346. I am looking for good numbers on the 402 with help from Rons ported 92 Fast. Stay tuned, numbers will be available in August. Should give some insight as to what the ported 92's with bigger tb's do with more Cubic Inches.

The build should be an absolute torque monster considering I am reusing my afr 205's that are milled to 59cc's. Imagine the throttle response.

Sorry if I hijacked.
