Jeremy....try the " Engine Shop " or "Hi- Performance" sub-forums, then try a search for details you are looking for - ie. motor mounts, trans mounts, rear-end selections, transmission options, boxing frame, Mustang 2 front ends, etc etc. As for parts Suppliers, try Chev's of the 40's, Jim Carter Truck parts, Bowtie Bits. Performance parts are everywhere - Summit Racing, Jegs, Edlebrock. Your Hot Rod guy should have a good handle on that stuff.
