I love my 7.3 and have had 7-8 of them but I was just suggesting the 6.4 for durability and dependability after the mods.

By the time he gets the 7.3 to make the pwer he wants he will be at a 6.4 used price tag.
7.3 will need a TW chip, Injectors, Exhaust, Cold Air Intake, gauges, possibly a HPOP upgrade, AND LAST A BUILT TRANS to hold the power and the heavy towing. So after the mods and built trans he would have $10,000 or more in just the upgrades to get the power. Then comes the factor of the dependability. One example is MattP's OBS was modded alot and only made 500 RWHP give or take but the truck had issue after issue.
The 6.4 seems to be doing best with the HP department and dependability after being modded.
