If the block isn't cracked, snap it up. That's a steal. If it's out of an 81 Suburban, it likely is a high nickel-content block (that's good) cast crank, and heavy duty 'thumb' rods. Probably undesirable peanut port heads, but for 300 bucks, it's a good foundation. If the tranny is an automatic, it's probably a TH400 with a bolt-on yoke on the output shaft.

I agree, a 454 with a transmission for $300, you better grab it while you can. with some fairly simple mods., you can turn that into a 400 HP or more engine easily.
