926hp on an engine dyno NA

we built an engine for a customer of ours that we took to texas to engine dyno.

the combination is pretty i shouldnt say mild but for the most part just normal aftermarket parts which it consists of.

440ci LSX block
Callies 4" stroke Compstar crank
Callies 6.125 Compstar rods
Diamond Custom Pistons
Stef's/ Jones Racing External WetSump System.
Gmpp Front Mount Distributor Setup
We Used Performance Induction Specialties LS7 Heads out of the box that flow 395cfm, we used xceldyne titanium valves and Pac Springs
Comp Cams Custom solid roller Grind Camshaft 28x/30x @.050 .9xx/.9xx lift on a 116lsa
Morel .904 Tie Bar Lifters Specially Spec'd by HKE
Smith Brothers 7/16 pushrods
Jesel Shaft Sysetem
Beck Sheetmetal Intake Manifold Setup for one ProSystems 1300 Dominator

it made 926fwhp @ 8100rpm and 657fwtq at 6300rpm

we are extremely pleased with how the engine performed.

I will Post Dyno Graphs and Pictures up shortly.

Once again, congrats David. What you've accomplished at your age is very impressive. I'm sure greater things are in store for you in the future.

It's going in a 02' SS. It should be nasty....for a full blown race car!!

IIRC he's running 2' headers.

correction he is running 2" stepped to 2 1/8" headders to a 4" collector those
dyno numbers are with just a set of dyno headders that i believe where 1 7/8

the springs are a special pac spring that we picked to work with these lobes.

it has 425 seat pressure and 1150lbs open. the cam has quite aggressive lobes
