I have a mild stock appearing non-hemi predator Ive been messing with. Billet rod, billet flywheel, ported head, mod 2 cam and valve springs. Just ordered a 390 carb and adapter plate. I would like to try it with the 390 carb on methanol. Do I just need to change the main jet, or is there other changes also needed to the carb?
Thanks for the help.
