Welcome to the 'Bolt Sean! The link you give requires a log in to look at your pix, best way to post them here is to link them in from a hosting site, like Photobucket or WebShots.
I looked in my own sorces for the engine numbers, they don't come up in my sources. Are these numbers the ones from the pad behind the distributor? Thoses would be the ones that will help ID them the best.
BTW, I read some of the resposes you got on the other site, I don't agree with the low pressure 216/235 as being "not worth rebuilding". I've messed with these engines for years, they are very tough, reliable engines. If you plan on going hot rod, then you would be better with the hi pressure engine, though.
