Low stress combo. Ai 219 high comp ls1 heads (milled to 56ish cc), forged l33/ls6 short block (346), BTR stg 3 ls cam. Fast 102/102. 437.8 rwhp @ 22deg timing. In the exocet. Ls1 heads can make power! Imagine some 243s or tfs/tsp heads... All in the combo.
u try higher timing to see if it picked up any ? most setups are around 28* or so on 93 octane at that compression without isues. my old setup on stock cubes with ported tea 1.5s at 56cc with a tsp 228 , 1 3/4 headers and 90/90 did 438/400 but we are just arm chairing it so it is still good numbers. it be a beast regardless in that little thing. congrats.

Thats a pretty small combustion chamber, it may not handle it. I still think between compression, a healthy cam, 102 102 it should make 450whp. Can't imagine drivetrain loss is bad in one of those little things.
It does. More timing just loses power. We tried all over the board. The CC is super small, they make it smaller when they weld the chambers and then they're milled on top of the that. Car also runs 20+ minutes at WOT on the racetrack.
It would probably pick up some with a more efficient exhaust setup. It's just 1 3/4 longtubes into a 3" y. There isn't a ton of space underneath to do much else though I've entertained trying to package 2.5" duals in the very small tunnel. Weight is also a concern.

Ai 219cc Hcr/ BTR 3 combo results... 
would be curious what cutouts would do off the headers.
