Yeah, but in my opinion, I dont see any real advantage over the 4" stroke, and it also increases rod angle, thrust load on the cylinder and a shorter piston comp height. Most ALL of the stroked sbm builds are cylinder head limited anyway. But again, that's just one guys opinion!
You are the first person to give me a legit answer to that question :) Everyone acts like 408 over 390 is a MASSIVE difference.. but 408 to 426 doesn't matter at all.. but without much backup as to why.
