I would say you might see 435 at the wheels.

I just meant the gears would not show as much on a dyno but you are making up for that and then some in torque multiplication for the track.

Gotcha; I'm not familiar with chassis dyno theory -- I hope to have it together by August/September, so I will revive this thread with the track results, good or bad. Previous best was 14.2 @ 98 with 400 FWHP 350 3.73's and a 4 speed manual (same 1st gear as a T56). 60' times were in the 2.0 range, but gearing was not on my side. I think I can cut several tenths off the 60' with the 4.56's.

This is incorrect. The standard 1999-2007 truck intakes are terrible, the Trailblazer SS style(on 2007+trucks also) truck intake is better though.
I just saw a dyno test that showed that the FAST 102mm LSXRT truck intake made 20rwhp over the Trailblazer SS intake on the truck forum the other day.

i feel the 1 3/4 headers will help move that heavy truck off the line compared to the big ones. the large lift/short duration figure should promote high volume in each primary so i see where your coming from, but the split will help to offset that.
