So absolutely no way the M300 or whatever will hold up? beef up the front end / add stiffer springs?
The motor will not be working anywhere nears its full capability/quite the opposite.. cummins 5.9 is a common swap, and the 8.3 is only 500 lbs more.. tranny is 150 lbs extra..wolfe10 wrote:
8.1 Chevy/GM engine-- yes.
Cummins 8.3/ Allison transmission-- NO WAY. Would way overload the front suspension. And, enough torque to do real damage (more than twice OE torque).
Beef up the springs and go for it! Besides, according to another thread on this forum, the switch to diesel fuel will make the rig handle better! ;)
