Right now i am running an 04 450r with a 13.5:1 comp piston, 3mm stroker crank, and a sparks racing head. I'm not really sure on the compression number but i am thinking because of the crank it is going to be more then 13.5 right?
I am using vp fuel c12 right now and it seems to run fine, but i can buy sunoco fuel for cheaper.
My question is should i use the "standard" leaded race fuel from sunoco or the "supreme" leaded race fuel? Also is there any pros and cons between the c12 and the sunoco and if i decide to run the sunoco is it ok to mix the two or should i drain my tank before switching?
