my problem

[TheX1992]

i have a cylinder that is bored .020. i have 2 pistons... 1. standard bore 11:1 2. .020 12:1. im not sure if i want to run race fuel. can i run premium on the 11:1? but its .020 off so i dont know. should i sell both pistons and get a new piston that can run pump fuel? i may just have to get a job and buy race gas

i doont think a stok 250x just bored a lil over and a high compression piston will need it.........just run premium with octane booster and you throw on oxginator and you can have your own race gas....................i run trick 101 with a lil turbo blue and a lead additive and klotz or maxima is my set up for the r ....................
