Jocko , the mounts for the 6 cylinder and V8 are the same assuming the 6 cylinder is NOT a 292 ! The 292 uses a different mount on one side . I replaced the 230 in my ' 65 with a 283 . The difference being the 6 cylinder has an adapter that connects the motor mounts to the 6 cylinder block. Otherwise , I used the original flywheel , clutch , starter , bell housing , z-bar , and wiring harness . You will have to get a V8 Z-bar pivot ball as the original 6 cylinder one is made in such a way that it can't be used . You can get one from a junkyard or order one from a vendor ( i.e. - LMC trucks ) . They aren't expensive and I replaced all the small items that are used with the Z-bar hookup . It really is an easy swap ! Check the LMC website (
www.lmctrucks.com ) and look at the appropriate diagram ( 1960-66 , page # 74 ) and you'll see all the items I mentioned . If I can help any farther , let me know . Good luck !
