Hey all, kind of bored so looking for some entertaining guesses on the new setup. Curious on fwhp guesses mostly (it is in my c5z so figure 12-13% for drivetrain loss with a 15lb flywheel and a standard RXT).

408, L76 block, 4.03 bore, 4" stroke
12cc Dome Wisecos, Gas Ported ported Rings (14.5:1 with an LS9 gasket)
Quench is around 0.046"
TFS 220 heads heavily worked over to be a 245. 2.1/1.6...360ish/270+
Holley Lo Ram with Dual Accufab 4500s on top, 1" plenum spacer
244/266, 640/640 on a 112.5
GZ Vacuum Pump (will run roughly 12 inches at 7k+)
BTR Shaft Mount kit with their rocker arms, 685 ultimate rpm spring kit
Johnson 2126 short travel lifters, Manton 11/32 pushrods
2" Headers, 3" collectors into a single 5" oval spintech pro bullet muffler
E85


I think that about covers it. My goal was 700 fwhp/600-610whp (but this was with the hi ram, shearer lid combo and a 103tb).. I believe with the top end change to the low ram and 4500s, this will bump that into the 730-740 fwhp range with the added rpm of the combo. I think ultimately, it will be where I want it and will run hard as hell. I don't track the car much, but I figure this should put it around a 138-140 car on motor.

14.5 compression, You must be planning to run Methanol ?
