Im not going to start a diesel argument but higher compression pistons isnt going to make you any more power in one either. hell, we lower it to prevent pre-ignition in the real high horsepower stuff because of all the fuel, which is what makes the power.

hood to see you look at the 6.5L seeing how stock is 21.3:1. the reason i recommended that motor and that piston combo is because it has been proven in alot of applications. they also make 400HP more reliably than a 4BT does.

i don't blame you at all stock they are complete garbage but they pretty much give the motors away now and they pretty cheap to build. to cut prices some more you could probably dish the pistons to drop compression a few points. i don't know if there is enough piston to dish down to 18.1:1 though
