The 292 was usually with a sm420 or sm465 right?

I have a 1/2 ton with a bad 250. I can either put in a 307 or a 292.

Any suggestions? The 6 swap would be much easier.

My truck came with a 250 and an automatic. I switched to the 292, you will need a different frame mount on the right side only. The theromstat housing is a little different than the 250 too. Also if you have PS on the 250, it will not fit the 292, other than that your good to go. Picture shows difference in housing.

I’ve got the passenger side mount. Everything else should line up where the 250 sat.

One other question, can I use the 250 radiator for the 292?

And you put AC in it, right? Did you install a fan shroud? I don't recall all the details. Just that I really like that truck!

Years ago I was given a 68 GMC 1500 with a blown 250. I located a 292 just because I figured why put a 250 back in when the 292 would fit ? I never could keep the crappy Chinese rubber engine mounts from ripping out. The three on the tree and stock 250 rear end imo did not play well together.

As you can see it has a full fan shroud, I bought this truck out of southern CA about 6 years ago and it came with a 3 core radiator and the shroud. Yes I added the vintage air, a 200-4R and the PS.
