i was comparing a big block to the engine he already has to a 5. 9. i am not a negative person but have experience working with 8. 3's and they suck. with your great experience with the 8. 3 you should know it wont get 10/12 mpg pulling. that's shows your knowledge. for his towing needs a 5. 9 will be more than enough. they do put 5. 9 in heavier class truck so don't give me the crap about towing heavy and high EGT's and heating issues. a bigger engine like the 8. 3 will need a larger radiator, air to air, transmission, drivelines, rear end. by the time you get all that junk in there you will be towing more than his 30,000 mark. have yo priced an 8. 3 engine, a transmission or any of the parts it would take to build a combo like this . he could go buy a used semi tractor and be miles ahead.
