Here ya go.
No clearancing is necessary with manifolds. Some slight clearancing was necessary with BBC truck headers modified for the Caddy engine.
A typical installation like mine involves moving the frame mounts forward to match up with Caddy 425 engine mounts from '77 era rwd cars. That gives plenty of room to route the exhaust from the manifolds (or headers) down. Frame mounts have to be cut to clear the steering center link rod and a new hole drilled in the crossmember to attach the frame mounts (just one is used).
Another method leaves the frame mounts in place and uses a 1/4" spacer plate to extend forward to Eldorado stud-style mounts. Either method works fine.
