cant find the right pistons!!!!
can someone please help me. i bought a supercharger for my camaro. my comp ratio is 10.3:1. im trying to lower that so i can run ^8psi and nitrous. im looking to buy some forged dish pistons. but im having trouble. all the pistons i have found dont go under 9.7:1 CR with my setup. i have a 383 stroker. (3.75" stroke, 5.7" rod 64cc chambers.) i am not looking to swap heads as i already have patriot freedom aluminum heads and i dont want to de-stroke my motor to drop the compression. from what i hear i am considering going with the 9.7:1 ratio and running a thicker gasket, possibly reboring to a .060 over the .030 i already have, and i have also heard that shooting meth can drop it. i have no clue. does anyone out there know where i can find lower compression pistons so itll save me the headache, or what should i do. ive checked summit, jegs, ebay, etc...please help! thanx
