getting tuned on tuesday, was told to bring the car full of race gas. the gas station by me sells 110, i dont plan on running the car all the time on race gas but i have the MSD timing retard box, so where maxing it and tuning it on race fuel then backing it off for pump. the car is a P1SC with the 3.4 pulley and a 8 inch crank pulley, 8:1 with ported LT4 heads/intake. was told it was 70 bucks or so for a 5 gallon can for c16. is it worth it?

 

If you have o2's/cats the (leaded)c16 will quickly kill them.

 

110 ftw.
