Badass!! If only somebody'd post something this in detail about B series (cough cough!) (EDIT: and hell,D series too,I just reread this..awsome stuff mang)

thanks for the awsome info w00t

Can you tell me if i resleeve an h22 can i get up to a 90mm overbore?

That string of measurements looks awefully familiar. Maybe it's just me but giving credit where due is generally considered honorable.

Link it to the original thread or credit the people who collected the info.

great info but whats the r/s ratio of the f22

Don't tell me you registered just to post that?

I got it off H-T. Hope you're "happy" now.
