I'm going a different route from most dieselheads. I'm having some custom rear springs made by Alcan for good weight transfer. Building my own ladder bars. Moving the battery, tranny coolers, nitrous bottle, and what not behind the rear axle. Dropping weight is also in the plan. Been running one battery and no grid heater for a couple years. Gutting the front axle. No t-case. Aluminum driveshaft. Wheels and tires that are much lighter than the typical mudder setup. No rear hitch assembly. No spare tire. Rollpan instead of rear bumper. Removing stock fan & clutch assembly. Installing a small electric pusher for those rare occasions it's needed. The truck doesn't have power anything for accessories but I will retain the A/C. We'll see what happens. Certainly won't be the fastest but I think a lot of speed can be found with light weight, loss of parasitic drag of turning the front driveline on a 4wd as well as stock fan, and most importantly, good chassis setup.
Motor won't be anything special. O-Rings, ported head, Helix2, springs, Mach somethings, some S300 spinner variant, and some combination of fueling/timing box(s) still TBD.
Tranny is an HTS unit with Suncoast 89% convertor and controller.
With slicks I am hoping to get it in the mid 12s with ~620hp on diesel. Who knows on the bottle. Building this truck just for something enjoyable/reliable to drive on the weekends that I can also have some fun with the average muscle car as well as those pesky Ferds.
So whatchyou got Robbie?
