Thanks guys, and if it helps any motor is .030 over, .557 mopar solid cam, Holley Street dominator intake, 750 mighty demon, 2” headers, and 4 speed with 4.56 gears.

12:1 would certainly up things a bit and I already run 100ll fuel in it so it wouldn’t be a huge deal.... but pulling up to the pump to fill it with 93 is a very nice thought!
