* Use truck to haul tractors and equipment, and daily driver and deer extractor. 230,000miles with STOCK TRANNY.......
next: good towable turbo, small sticks, tranny work, and a wire tapping fueling box.
Ummmmm I think you should really -first look into that tranny work
..... then
upgrade the performance of your engine......
But I also think a HX-40 or a Super40 are towable, Be sure that the shaft bearings has been modded,
I would look at DonM's
Formula 1 line of injectors, you could go with a set of Don's Mach 2.5's and be very happy....
You're gonna have to stay away from turbo's that are known to have surging issues.....
