jimfred,

Why don't you just drive down to Southeast Engines down off Boldercrest and get a 292 short block. Will cost you $530 + an old core if you can find one. No core will cost ya a couple hundred more.

If that old 230 (or 250) has passed the midpoint of its life cycle then I think it might be a good idea to consider investing in the 292. That is, if you want to stay with a 6.
