As long as you put a good set of rod’s, pistons and rings in the motor, you will handle 20psi + all day long with that compression ratio. 10.1 really isn’t that much compression to be really worried about with these motors.

I have new bearings, if they dont work for the new rods, I sell them or keep them on the shelf for the next motor built at the shop.

Scat I beams, or for $150 more the H beams. :dunno

And since I am going to run the shorter rod, the 6.1" my compression will be in the mid 9’s so it will help a bunch too.
