So from what I'm hearing, it can be done.
Seems GM changed the bellhousing crossmemeber at some point in time (54 or 55?) to one that will connect to newer V8 bellhousing. As I have a 58 my crossmember is good to accept the new bellhousing.
The 292 won't bolt up to the old bellhousing that the 235 uses, but will bolt up to the newer V8 bellhousing. Did all the V8 bell housings (of the time when they made the 292) bolt up directly to the SM 420? Does the SM 465 have the same bolt pattern as the SM 420?
The motor mounts to the frame will have to be fabbed or at least modified from off the shelf ones to fit my 1 ton frame... that shouldn't be too tough.
I've heard you can fit the mechanical fan in, but may require some modifying of the fan shroud and fan spacers.
Still not sure with clutch linkage, but I am optimistic. Not sure with starter. May have to do away with my foot stomp starter.
Now to find a junk yard jewel 292 with bell housing. The search is on!
