I have a list of stuff in my signature

No idea how it would do on the stock motor. I had the heads ported and milled. Upped the compression ratio to run better on 100+ octane.

I've heard that high octane gas wont do much in a hemi unless it has a custom tune to take advantage.
Yup but it will prevent any timing from being pulled do to knock. When I ran 93 in my JGC 5.7 I barely saw any knock but on 87 it was knock knock knocking on heavens door (more like pings) on hot days in traffic.
