If a 4" stroke forged crank becomes available it would be easy to have it offset ground to 3.75 with a 2" rod journal. I have stroked a couple of 3.75" cranks to 3.875" with good results but going the other way with an offset journal would be a great way to go as you would loose some friction and have a slew of SBC rod bearing choises
I think a 4.31 x 3.75 " combo could make 900 hp N/A with the right heads,like the new KRE High Ports. Would be a piece of cake with Super Chiefs or Tiger heads.
