3.23 or 3.55 Behind a 318
I just ran drag week with a 26.5” tire and 3:73 gear with my 410 ci LA. It was fine, car usually runs 4:10’s which is a bit much on the highway. Really depends on whats important to you? I never cared about mileage. So for me, it’s does it spin it so much it gets hot on the highway or you can hear the valve train weeping in pain. No? Than it gets the rear gear that makes it go the fastest! 4:10 at the 12.2 to 1 would have made it run to warm for my liking.
