Wow, very impressive. Although I won't be running such nice heads, I'm hoping for something similar in terms of numbers from my 383. I'll be running the 1900 with a 2.8" and IW pulley setup along with a healthy cam.

Those are great numbers to start with. Looks like traction is going to be even more of an issue now.

Those are killer numbers bud!! Cool to see that 1900 pumping out the ponies!

So how do you like the IW pulley?

Ive been contemplating dropping to a 2.7 and an overdriven crank pulley myself, I'd like to see 12 psi on top end.

Awesome numbers!!!! Can't wait to see what it does at the track

Do you know what the inlet air temps were?

It should make 2 more psi back home at sea level and as much as 8-10% more power once broken in. It should put down a nice number at the track once she's dialed in.

BIG Thanks to LEP for building this nice motor and hooking me up with a blower cam, WCCH for their excellent work on the heads and Joe (LeftCoast32) for doing the dyno tune.

I need to figure out what I'm doing wrong. If my fuzzy math is correct, I think you're pushing 4.3% more air than I am with TVS2300 and 3.1" snout pulley. You have a slighly bigger cam and probably better heads (Livernois stage 2 243's on mine). What c/r are you running? LSA on cam? Have you done any updates to the I/C circuit? I'm considering adding a small radiator to the I/C circuit with e fan(s) in my truck bed.
