Engine options? Threw a Rod.

[Mullet863]

So, my 65 Suburban, "Rusty Betty" as I nicknamed her, made it about 60 miles since purchase before throwing a rod and totally seizing up. I'm going to attack the engine this weekend, but I'm not hopeful.

I went into this "project" not knowing a lot and it appears I'm in over my head, but I'm not going to give up.

What are my options as far as engines, I have a few options in the area, either a rebuilt stock 350, a 327, or ????

Definitely not happy with the amount of money I've already dropped on this thing, but like I said I'm not giving up. I'm looking to keep this part of the project around 2k.
