I just bought a Ford 460 New Engine for my 1966 Lincoln Continental. It has a 462ci V8 in it and I was told I would need new motor and possibly transmission mounts for the new motor. Specs below:

Complete rebuilt ford 460 1)block hot tanked, magna fluxed 2)block bored .30 over, honed w/deck plates sunn 3)new brass freeze plugs 4)new sealed power bearings 5)reconditioned rods 6)decked block, line honed mains. 7)reman heads decked triple angle valve job comes with edelbrock 750 carb. Weiand aluminum intake HEI dist built to run on ford, new water pump, fuel pump, all pulleys and brackets even edelbrock air filter, exhaust manifolds and a engine swap kit to fit this 460 into a foxbody chassis.

I was told by a mechanic that the engine will fit but he recommends a new transmission. I wanted to ask another mechanic or someone that has more knowledge than I do at Lincolns. The Transmission I have there I assume is a C6 with 68k Miles on it. I was thinking to put a rebuilt C6. Should I?
