Engine/Transmission (1998.5 - 2002) South Bend Con OFE or MU 13-1.25 Con FE(W)

[tmckenzie]

Whats the breaking point and biggest determining factor as to when you "Need" to go to the bigger MU 13 Con FE or FEW vs. just sticking with the Con OFE. Look at sig for details but I want to be capable of upping the HP and FT-LBS. After clutch goes in injectors would be my next project. I tow very seldom but I want to do my clutch right the first time so I only have to do it once, but want to do the most economical as well. Any suggestions?
