So after over a year of building I finally sent my LS6 swapped Nova to the dyno was a little taken back by the numbers.
The numbers were pulled on a dynojet tuned on CA 91 oct
407hp 373tq

Stock LS6 short block
Stage 2 ported 243 heads from TEA stock compression
Tick performance street heat #1 cam
Fast 92 intake
Fast TB
Upgraded injectors I don't recall the flow but should be good to 550
Speed density
Long tube headers
Under drive pulley
4L60 with a 3k stall
Ford 9 inch 370 gears.

I know with the automatic I was going to lose some but damn does it seems like something is wrong with these numbers?

It's not out of the realm of possibilities IMO. Take it to the drag strip and see how it runs, that's all that really matters. The story is never complete until you get a trap speed.

I get that the numbers dont matter in the big picture It just seems that its off a good portion from other build i see and read about with like setups.

Probably would have been better off with the Total Engine Airflow Stage1 heads and milling them .020-.030 The 229 port volume has slowed the velocity of the flow. Stage 2 heads are better on a 4" bore or larger.
