287 Pontiac replacement in 55 GMC

[spitfire_er]

I tore into my 287 today after failing to get it to turn over. The truck sat outside for many years, but everything is complete and the hood was on along with the air cleaner.

Over the years it looks as though water vapor has gotten in there and put a nice layer of rust on everything under and inside the heads.

I'm sure I could clean it up, but I'm not sure it would be worth it.

Other than the 316 or the 347, is there another engine I can bolt my hydramatic up to without too much work. I know the engine mounts on the 287 are a little odd being in the front and rear bell housing, but I can always put new mounts in if needed, but I don't have a welder handy, so a similar engine swap would be best.

I'm just trying to get it running now as quick as possible, as cheap as possible.
