Gotta love improvements.
Remember when the 1989 Dodge Cummins with 3 speed trans and a whopping 160 Hp/400ft/lbs was the cats meow?

Just used my 1992 to tow our toy hauler to a campground for the weekend. Being in California it does all right and while I see guys towing at 75mph that's just not my style. Also the fact my truck only goes about 70mph helps ??

I've never had it on dyno but she's got 50 horse injectors, HE351 turbo, full 4" exhaust including down pipe and a few other odds and ends.
