I believe DASA makes a 500cc kit, but its 12:1.

www.dasaracing.com

Athena makes a 480cc kit @ 10.7:1

Might want to check out www.maxpower-engines.com

They make big bore Ice Cube cylinders.

He can get away running pump on a higher octane than that though.

Yeah, that is what I figured. In most cases, though, you can get away with the 12:1 that most offer.

MAYBE YOU CAN RUN A LITTLE BIT HIGHER COMPRESSON ON PUMP GAS WITH EFFECIENTSE OF THE COMBUSTION CHAMBER. BUT I DON'T KNOW EXACTLY HOW MUCH. I JUST WANT TO BE SAFE NOT SORRY. I DO ALL MY OWN WORK AND AND IF THE PREDITINTION FROM COMPRESSION BEING TO HIGH ON STOCK TIMING CURVE,IS TO LIGHT WERE I CAN'T HERE IT IN THE MOTOR. I CAN BE IN REAL TROUBLE AND TEAR UP MY REBUILT MOTOR UP.
