Okay, just a bit of a tangent about funding a toy car since you've dangled the bait.

If you're not hot, horny for a 327 of specific vintage/origin, and 350 sbc components are all over the place, one option would be to peddle that 327 to someone in the Vette restoration crowd. Correctly numbered/identified/date coded Vette stuff can go for what some consider crazy money (and you certainly got in at a right price). I don't follow that slice of the hobby directly so you'd have to do some research (or maybe someone here knows), but if everything lined up well, you might be able to fund a well rebuilt 350 short block or better from the sale of the 327 parts.............just sayin'.......
