Extude hone stock manifold is the *only* way to fly. Cheaper than a tubular crack a fold, more efficient, and real deal boss. Plus if you go external you can't beat it.

If it was a load bearing dyno you'd see it in the 3500-3800 rpm range where I hit full spool. With the 4.6 Final Drive the car is a rocket.
I went 11.65 @ 120 first time ever on slicks. A good driver would have that in the 11.0-11.2 range at the same power level/with my new boost control.
FWIW: My newest chip makes 12 psi at 5500 rpm. Thank you JWT.

I'm expecting 350whp on 18psi. Going to be on a dyno dynamics also so it will read pretty low. I think.

That's a pump gas number, my water injection is not setup to make more power, just detonation resistance. I don't trust a produce aisle sprayer pump.

You mean 40 years right? I wouldn't call LT1 heads anything special, nor Vortec.

If you insist on the .86 housing,
JWT S4 if you wanna run 20-24 psi. JWT S3 if you wanna run 18-20 psi.
