There are *no* "mid '60s" 385 series engines.
They started in 1968.
385 & 335 series engines are the only ones to use this pattern
So, you have a 1950's gearbox bolted to an engine pattern that didn't start until the mid '60s?
'Cause it wasn't until late 1964 ('65 Model Year) that the 'Windsor' pattern came into being.
I guess when I said mid 60's, I was just guessing. I don't have anything as of right now, but am actively looking and was just wondering if I could go as far back as '68/9.
Both the RTS and the RUG SR-OD (Single Rail 4 Speed O/D) that preceded it are "weak sisters."
One speed shift, you can kiss the little darlins' good bye.
So I guess after reading this that the best thing I can do is source a T-19? Will these bolt right in, and by that I mean does the crossmember have to be modified, will my current gear shift lever work?
I am DUMB DUMB DUMB when it comes to transmissions. It's one thing I could never get in to. I guess now I'm kicking myself for that.
A diesel bell is not a 460 bell, same casting, drilled differently, only the top 2 holes line up. On a diesel the starter bolts to the adapter plate, not the bellhousing like a gas truck.
As for the Clark transmission thing, I recall seeing that in the decoders in Chiltons books, yet I have never actually seen such a thing.
You will need to change driveshafts completley, 2wd ZF's are fixed yoke output, so you you need a slip shaft, a 4wd with a fixed yoke could be a possible donor for shaft parts.
The only hitch with an early engine, is that they are internal balance, and the ZF uses a 12" clutch. You need to have the ZF flywheel zero balanced or a zero balanced one drilled to suit the pressure plate.
I'm looking at the parts illustrations for the gearshift mechanisms but the descriptors for the various transmissions don't coincide with what I'm used to hearing them called. In other words, I don't see an illustration for the T-19. Is it called something else?
I suppose I should just stick to hunting down an engine of the correct era. Probably will make life a whole lot easier.
Finding a donor 460 truck would make your life the easiest. In fact, using the donor frame would make it really easy, since it will have the dent in the crossmember for the 460 oil filter. The donor will also have the 460 with the proper oil filter adapter for clearance, the correct crossmembers, bellhousing, driveshafts, fuel system, heavier frame, larger rearend to handle the 460, heavier frontend to handle the weight of the 460, etc.

look for a M4HD under a 250-350 truck with the 460..
Mine was marked 13-09-065-911, if that helps at all.
