does anyone use 100LL av gas ?

I've had a 413, and a 451 with 13.5 to 1 C ratio. Both ran great on 100 LL. The 451 would run fine on a 50/50 mix of 91 and 100, .037 quench, mixture on the rich side, 38 degrees timing, 509 cam with a late closing intake valve event. Also keeping it COOL helps. All these factors added together allowed me to run the high compression 451 on the street or track with no problems. And that motor was a screamer! 100 LL WORKS GREAT! Even when mixed with 91 premium. Oh yea, the thin air in Colo helps too.
