5r110 or nv5600 for fun street truck
Newbie here, so first off hello. Not a dodge truck, but 2nd gen powered mutt.
I am building a light weight semi truck. Target of 8000lbs or less, 700hp, 1300ft/lb torque. 6bt ppump engine, aam 11.5” rear end, small kenworth day cab, custom built frame, custom built 4 link suspension, lo-pro 22.5’s in front, supersingles in back. Obviously have to run 10 lug adaptors. I want a fun street truck that I can use on a drag strip, tow moderate loads, and daily drive. I am building the frame to handle anything a 1 ton p/u can.
The rear suspension is a mix of aam rear axle, trophy truck sized ballistic joints, and doubled up pro-mod mounting plates. 2” DOM 0.250” wall for the 4 links. The suspension is built to take anything I can throw at it. Right now it has 3.73’s, not sure what ratio I’ll use yet. The front is built up duramax independent suspension. I have designed it at 6” ride height and a solid front axle wouldn’t allow me to get the truck low enough.
The 6bt came out of a low hour low mile freight liner, I traded a handgun for the engine so I think I did really good. I have installed a KDP blocker plate, and resealed a few gaskets. I will handle the performance parts once the truck is rolling. The engine did not come with its transmission adaptor plate. I’m almost at the point where I’m needing to decide what trans to use to mount the drivetrain in the frame.
I need to use my money as intelligently as possible, I’d love to buy a sun coast built trans, but I can’t spend that much on one item. I already have a good running complete diesel 5r110 trans/ecu/wiring harness that cost me basically nothing that I’m considering using, or maybe buy a used nv5600. Running an auto vs a stick makes no difference to me, they both have their merits. Which do you guys would think would last longer and cost less? Considering I have no drivetrain parts besides an engine and my power goals. I drive like an a**hole so, I’m gonna abuse this thing till an inch of its life.
