Never tried this before!

The big reasons to NOT buy Schumacher mounts when you have a spool mount V8 k-member is that you can run stock mounts, it's considerably cheaper, AND the Schumacher spool mounts require you to drill a new hole for the large bolt and install that bolt while the engine is hanging there (PITA).

Do yourself a favor and spend some time in the tech archives at www.bigblockdart.com. Mark isn't completely correct on the mods, though. Both motor mount saddles need to be moved back.
