I'm not convinced that 428 blocks are in that range. CJs, maybe. But yer average 68 Galaxie sedan motor, .020-.030 over and with no faults? Nah. Maybe $1k for a very good example. If you have to have a PI or CJ or SCJ... well, you're going to pay for it. Just as if a 427 top-oiler isn't good enough, you're going to sell another car to pay for a good SO block.

I'll concede that good 390 blocks are somewhere between $0 and maybe $300. So the difference is somewhere between $500 and maybe-maybe $1,000... which, I will maintain, will show up come second-buyer time.
