How would I go about trying to drastically increasing my compression ratio on my 770
I'm looking at maybe boring it out for the pistons used I a gm vortec 5.3 as the bore is
similar to the 3.75 over bore kit. I'm trying to find the pin diameter for each as well as
piston height from pin to top. I know there is a possibility to taking a .100 off the head
too. The gm piston is around 9.5-1 compression. That's my target is 9 or 9.5
