10.2 : 1 compression 360 at sea level. Options?

Run 93. I ran a 360 @ 9.8-1 with J heads and the MoPar purple 292/.509.
Manual trans, 4.10's.

You can run a .054 Fle-Pro to cut a 1/2 point out in compression.

Possibly a better cooling system. I ran a fresh recored radiator, MP viscous 5 blade fan and OE shroud.

You may have to limit total timing a few degrees. Worst case tha is.
