    Default 602 crate and 4412

    What fuel is everyone running? race gas or pump premium?

    Good carb builders will be able to help you with that when they do the carb. Yours might be able to offer a suggestion.

    He is telling us 110 race fuel. I don't doubt him, just didn't want to spend the money if it wasn't gong to help. We have been running good with pump premium, just trying to get a little more

    Ask your carb guy about Sunoco EXO2 jetted 12-15% richer than you are now.

    EXO2 works well but it isn't cheap. 110 in a 602 is pretty outdated especially with a 2bbl.
