thanks for the info it was very informative will post pics and dyno # when i finish. does anyone know what i will be looking at hp and whp with eagle rods and je pistons 10:1 and a gsr head.

 

probably about the same as or a little more than a stock gsr. you don't make power with pistons... you alter ve thus creating power... since you lowered the compression, you'll probably make less power than stock pistons. unless of course, you're turbocharging or supercharging. or lowering your compression and milling your cylinder head or somehow altering compression.
