WANTED: 455 BOP or 454 BBC

[80_OLDS454]

Looking for a running 68-72 Olds 455, 70-72 Pontiac or Buick 455, or 454 BBC. Preferably complete carb to pan, including accessories. Anyone know where I might find one? ANyone have a grandparent with a 70 Buick electra? A complete "boat" would suffice. Looking to spend < $1000. Again running condition. Mileage doesn't matter as long as it has decent compression and doesn't burn a ton of oil.

Thanks,
NS
