8.3
Hey, oneshot, you blew your 5th grade math. a 454 chev is 50 cubic inches SMALLER than an 8. 3(504 ci). the 8. 3 stock makes DOUBLE the torque of the 454. So, whats your point? ANY cummins is WAY more durable than any gas engine. the 8. 3 is the basic engine in many 40 ft. motor homes, and they`ll pull 10 / 12 mpg while towin` a toy trailer and not have any heating or egt issues. True,you can BOMB the hell out of a 5. 9 to get a 1000 ft lb/torque engine but you won`t be pullin` a 25,000 lb or 30,000 lb load up hills all day without egt and heatin` issues. A mild tweak om a 8. 3 will be tons more reliable than any gas engine or BOmbed 5. 9. If he wants to put an 8. 3 in his truck for HEAVY HAULING, the 8. 3, properly installed, would one *** kickin` combo, IMHO. DON`t be so negative!:-laf:-laf:-laf
