going to start running a 3:1 mix of 100LL/91 octane in my 557 but am not sure which way i need to adjust my timing and jetting for this different fuel set-up, here is what i currently have going, which has the plugs looking pretty good
4100 ft elevation
557 11:1 cr
BT aluminum heads ported and polished with ford exhaust port
Comp xr-292-r solid roller cam
victor intake
Pro-systems 1150 Dominator with a 1" supersucker carb spacer
88 on the primary and 96 on the secondary jets
32 degrees of total timing
Thanks in advance for the help as always
