if you want to spend 4plus dollars a gallon for higher octane gas then 12 to 1 is ok,,,

i say 10.25 is plenty since your not racing or anything,,,

nope. the 10.25 will run on regular unleaded gas but the 12:1 will need high octane shizzle. you're best bet is to go with a 10.5:1 compression piston. besides, the 12:1 piston will leave bruises on your shin from kicking it over.

alrighty then if the 10.25 uses normal gas then that is my choice. well mabye. is there a hugh difference in powerr going from the standard to the 10.25? and is there a much bigger difference going from standard to the 12.1?
