I have a 69 Charger w/ a rebuilt 383. It is .030 over, 906 heads, performer intake, and a holley 650 and headers. THERE IS A PLACE NEAR BY THAT SELLS 110 OCTANE RACING FUEL. I HAVE HEARD THAT IS DOES SOME GOOD to put some in once in a while. Is there an advantage? what does it do for me? if so, what mix to use ???
