Built roller 468 jet tuning advice
I recently picked up a 77 Roger's jet with a fresh built 468 with around an hour of break in time on it. It's all forged internals, full roller, 12-1 compression (yeah, I know. Not the ratio I would have went with personally), Dart intake, Edelbrock 850 and Basset Headers. The last owner was running it for short periods on 93 pump gas. I'm trying to decide if I'm gonna run straight 110 race gas 🤗 or if It's gonna be a bad idea to cut 110 with 93 non ethanol. Or I could even go the 100AV option. Any suggestions? Can specs attached

That's kinda what I was thinking/afraid of. That 110 ain't cheap. It does have 2 20 gal tanks. I had the idea of running 110/93 50/50 mix for around 102 octane in one tank for cruising at low RPM and warm up and then switching to the 110 tank for any higher load pulls
