New here, but I've been on FTE and Slick60's for years.
I put a 302 in my 64 F-100 several years ago using a TransDapt crossmember kit. Those are still available from several vendors. Dennis Carpenter, Autokrafters, Speedway Motors, etc. They are cradle type and can be bolted or welded in. THAT'S the easy part.
Good luck, Phil
