    Flywheel for a 1977 425

    Hey I just picked up a 425 caddy, and I'm trying to put it in a 4x4 truck infront of a 4 speed manual. Now I was told that a BOP bellhousing will work on it. But I can't seem to find a flywheel for it, probably because Cadillac hasen't made a car with a manual in so long. So I am wondering if anyone knows if there is a flywheel off of a Buick, or Olds, or something that will fit on the crank flang of the caddy motor, or if I need to get one made. So if anyone knows a trick to putting a manual behind a 425, or if any other GM motor has a similar flywheel bolt pattern, please let me know. Thanks a lot

    As far as I know you have to get a custom made flywheel made for the Cadillac. You have to go to Potter or MTS to buy it. You also need to modify the crank.

    Here's a link to the caddycarlo web-site and he shows how to do it.

    Here's a flywheel for you on eBay but I bet his reserve is at least $400

    Well I was wrong there, the reserve was met at $180. This would be a good buy if it would just stay put.

    That flywheel only uses a 10.5" clutch? Even guys with a 350 want an 11" one, and I thought the flywheels from MTS and so-forth allowed a 11" or larger clutch to hold up to a 500ci motor.
