Dave,
Yes; the truck block is setup on the sides at the front of the motor for the mounts that go to the front cross-member. There are no side mounts (half way back) for the car mounts. The Belair motor has no mounting place at the front sides of the engine but has a triangle shaped set of 3 holes about half way back for the side mounts.
I'm wondering if I can use the conversion engine mounts that fit a V8 in the truck like what Chevy Duty sells. Any ideas?
Jerry
