Gas Choices?

[zeus54]

I HAVE BEEN PLAYING AROUND WITH THE TIMING ON MY CAMS WITH THIS 440 KIT, IT SEEMS TO RUN STRONGER WHEN I RETARD THE EXHAUST CAM 1 TOOTH ON 93 PUMP GAS, BUT WITH OUT A DYNO RUN I DON'T KNOW FOR SURE HOW WELL ,BUT TO THE POINT I WAS THINKING ABOUT TRYING SOME RACING FUEL'S TO GET SOME MORE PONIES SO WHERE SHOULD I START?VP OR KLOTZ PERHAPS AND CAN I GET DO THIS WITHOUT HAVING TO GO TO A HIGH COMPRESSION PISTON?AND SHOULD I BE MIXING IT WITH PUMP GAS OR JUST STRAIGHT UP

If you don't have a HH piston, don't bother with race gas. Just use Sunoco 93, it's just as good without an HH piston.

you dont need an hh piston. U jsut need a piston with hi comp like 13.1 or race gas will be useless
