This year we built a 512/400 at 13:1 and we will see if we can get it to run crap 93 with octane booster....
Me thinks you be messin with faith with that combination Maybe try E85 instead I'll have another post soon about a 518 C.I. 400 block I dyno tested this week on E85 after I figure out what part went south in the ignition system on the dyno yesterday Hopefully I'll get it figure out this weekend
We are starting on race fuel and going from there. Its mild enough to street it.....But we want to go faster than 9.70 on the track.
Race/93 mix at the track, pull some timing and run 93 on the street😀
