OK guys, hear me out, im haveing a heck of a time finding a big block 4 speed bell housing for a truck that isnt 10 million dollars. I have a mill, I have the tools to make a adapter plate that goes from the 833 pattern on a car bell housing to the wide truck pattern. I was thinking of using 3/8 plate. Im not worried about spline contact, or clutch pivot stuff as I can make all that work with simple tools. Do you guys think Ill need a crank flange spacer to get the clutch and pressure plate correct or is 1/4 or 3/8 not enough to worry about.
Its a farm truck, and a ugly one at that, but I really want to use up some old 383 parts I have laying around.

If you also have a welder, I'd say you probably don't even need an adapter. Just weld on more material as needed, then mill off whatever you don't need.

How much larger is the truck transmission bolt pattern than the car pattern? Bell housing cast iron?
it's ok to butt heads, just don't do it with a butthead

The obvious question is exactly what truck transmission are you trying to bolt up to the big block?
That might help with trying to find a bellhousing.

Even a old lLakewood will set you back $1-3 hundred but you could drill /weld whatever onto it with no problem

It would be easy to make an adapter plate from 3/8" then you could use your mill to take some off the face of the bell to compensate for the adapter plate. You would just need to get some 7/16 countersunk bolts to mount the plate to a standard bell. Gus

If this truck is used for ordinary driving and not like dump truck or pulling heavy equipment I would think the 1/4 or 3/8 plate would work . Setting back that thickness shouldn't affect the pilot bearing or throwout bearing but dimensions should be checked.

It's still expensive, but no fabricating necessary. I've had a few cast big block bells, sure wish I had held on to them.

Your time must not be worth anything to be willing to do all of that work, those bellhousings usually run $200 from a lot of people. try a craigslist search via https://www.searchtempest.com/you can search nationally. Or put out a want ad, someone probably has one on the shelf and would be willing to let it go affordably. Tim
