Hank:
BUT he has 15:1 compression !!!! I'd say that would be a little stressfull on the thin bores. His seems to be holding up quite well. I'm looking into the 4" bore and having my crank stroked to 3.75". This would make a 283 cid engine. I only want to run 9:1 compression, not nearly as hard on those thin bores. I have a early 230 block which should have a lot thicker walls than a first year 250. (well, at least I hope so) ;\)
Now if I can get the money saved up to get Edy's head and EFI intake up here to Texas..........
