Mark,
I wish you luck in finding a 427 block. Seems that "old" blocks not requiring a sleeve or two and std. bore are
getting increasingly harder to come by. Anyone fortunate enough to have anything laying around
is very reluctant to let go of it because finding a replacement is near impossible especially if you want to build
a numbers correct engine some day. By the time you get a used block ready to use you can probably pay for a new block but it will
still need about 700 plus in machine work to get it ready to run.
I recall a while back you were trying to find a complete 428 engine or a block and I assume you were never able to find one.
Seems all this old iron is becoming more scarce. Even hard to come by a good 390 block in some areas.
Robert Pond and BBM are probably the only 2 right now producing iron blocks and last I heard they are both out of stock.
Brent used a Pond block on my 511 TP and no issues with it if that helps anything.
Hopefully if you keep asking someone will be willing to turn loose of something you can use.
Good luck
PS you are not a hoarder!
