A few weeks back I purchased this factory diesel 1983 f250, with a 1988 7.3 na swapped in with a the factory t19. I cleaned up the cherry apple paint And pulled out the driveline as a builder to be used in the shop truck I picked up a diesel C6 for use in this truck, I had a thread awhile back to see if the community would like to see a dedicated race setup or more of street/strip setup. Seems the race setup won the pole so I will be going that route. What I have in mind is to use the idit from the shop truck, bored 40 over for a 7.4L (452ci) displacement, solid block with no coolant passages, R&D cam, 3M injectors, custom 10mm Db2, NCC 1k water to air, CDD intake manifold, off the shelf s300 SXE, fed with meth and nitrous. Ive decided Im going to keep leafs in the rear just to get some more experience tuning a heavy leaf spring setup, so I'm likely just going to bolt a sterling 10.5 into place since I know it will handle the power. Ive got some old school hot rodding tricks I want to try and implement with this engine build, I think I can drop a good 1500 grams from the rotating assembly which would be making an extra 35 hp at 4000 rpms, but more on that once we get to the engine building. Id like to hear some thoughts on trans options, Im really considering a simple combo with the c6, with a Broader Performance manual valve body & trans brake with a 2200 rpm stall converter. I know I would be losing a lot of power with this setup if I ever wanted to put the truck on a dyno, and without lockup I'm losing load on the engine which is going to pull less fuel from the pump, which fuel will be my limiting factor for this build, but I could build this trans setup for around $1000. Which leaves more funds to be spent other places, like the engine, safety and suspension. The other option I'm considering is using an e40d that I already have and is built to the updated spec. I would need a triple disc converter $700-950, a USShift controller with the options I want $775 and a billet input shaft for $250. The benefit would be for $2000-2500 I would have a much stouter trans with lockup and overdrive. I would lose the transbrake option, but it sounds like they are working on that as a feature for the quick 4 pro update. For the next few months, I plan to mostly be working on the chassis, stripping out the interior for a roll cage install, moving things around in the engine bay, building the turbo kit and seeing how much weight I can pull out of this chassis.
