V10 in 65 Cuda

Before anyone goes off on me, this is a serious question. We're entertaining the idea and would appreciate any experience. Has anyone done it or heard of it?

If so, mods encountered: firewall, mounts, radiator, tunnel, etc? Will have harness, ECM, etc. Will fab headers, cross mounts, wells are cut for headers from small block, shorten shaft. Also, is already an 8 3/4 diff.

Mainly just interested in the compartment and tunnel issues. This is an all aluminum/alloy model, BTW.

OK, fire away.....and thanks in advance.
