Bolt on GTO vs Bolt on 5.0

Bolton LS2 GTO's with a auto dyno in the 360rwhp range, but the FAST could change that up another 15-20rwhp maybe. Dyno any more than 380rwhp and I'll it a happy dyno.
I haven't seen a 5.0 do a dyno run yet (odd actually as I go to alot of dyno days) but with his mods -JLT intake, LT Headers, Catless exhaust, Tune- shouldn't he be in the 430-440rwhp range?

I've seen bolt on a4 GTO's dyno 360-370whp with stock intake manifold.. I feel that my 393hp is pretty accurate with the Fast, maybe a little happy.. I expected 385/395...
Bolt on 5.0's dyno around 420whp with those bolt ons... He's also on a bama tune, but don't let that fool you.. Those bama tunes are no joke he ran with a full bolt on/dyno tune 5.0 when he was just I/E/Bama.. Even pulled him by half a car one race...
Both are my buddies && both can drive.

I figured ~380 for the GTO and ~410 for the GT. But I feel we can comfortably agree on a 40-50rwhp difference.

I picked up 2whp/10lb ft from a ported ls2 to a ported Fast 92. You wont see anywhere near the gains you think from the fast. The car ran a little better than the 2whp might suggest but it sure didn't show it on the dyno.

how much did you pick up with the ported ls2 intake over a stock one?

They are known for gaining throughout the whole rpm range not just at peak... Everyone seems to say the SOTP gain is a big difference compared to the dyno results.
I got my headers && tune done at the same time so I honestly don't know
