Oh well, pretty good numbers for 7.4 DCR. Might mill the heads to get to 10.3 to 1 if it will help.
Desktop dyno help?

Offenhauser Single plane intake (tripower) 816 CFM carburation. Hooker sidemount headers with Maxflow mufflers. Like to check against my actual dyno numbers.

Already got the cam. Custom ground on 114 LSA. Wanted a wider, flatter torque band and a little extra for the nitrous. Might bump my NOS up later. I knew I would sacrifice a few HP with the wider LSA but figured better bottom end and midrange torque would make up for it in the RPM range I usually drive in. The compression can be bumped slightly by milling the heads and the installed CL can be adjusted. Those are easy changes I can do now to get better results when I assemble. Ready for assembly.
