440 Manual Trans Swap, 1974 W200 Powerwagon Parts Req'd? - 11/17/15 01:08 AM

Considering a Future Engine swap from a LA 360 w/ NP435 Manual Transmission to a 440 USING THE SAME NP435 Manual Transmission, in a 1974 W200 Powerwagon.

What extra parts are required? Along with a suitable 440, internal/external balance issues aside, Here is a Required Parts List as best I understand, but is this Complete/Correct?

1) BB Bellhousing and bottom cover
2) BB 143 Tooth Flywheel
3) BB 11-Inch Clutch
4) Rear Sump Oil Pan w/ Pickup
5) Center Dump Exhaust Manifolds
6) Small Diameter Pwr Brake Booster
7) Drill Crankshaft for Pilot Bushing (if cast or non-manual Trans crank)
8) Radiator with inlet/outlet correct for BB
9) Motor Mounts
10) Transmission Input Shaft? 1 1/8 Or 1 3/16 inch? 18-Spline, is that correct?

So, Is this List Correct/Complete?

I am in the process of swapping FROM a 440/4 speed setup TO a 440 727. The truck 440 in my 1975 Power Wagon has a forged crankshaft. this is almost certainly a truck-only thing since all other late 1973 and newer 440s were cast crank mills.
If you find a 440 that isn't drilled for the traditional pilot bushing, you can use that roller bearing that fits into the torque converter recess in the crank. I did this in my FrankenDuster 360/4 speed setup.

I'm near Sacramento. There may be someone closer to you but if not, I will be selling everything pertaining to the manual trans setup including the steering column and the clutch & brake pedal assembly, all linkages, etc. PM me if interested.
