you can save some of your pocket change by useing the fe motor mounts mounted diagonally to the block of the 460 and it will sit right in the fe frame mounts if you are useing manifolds you will have to trim the upper corner of the mount to clear them. i also cut the stud off the mount drill all the way through and run a grade 8 bolt through and tack weld it in place this will assure that you will not rip it loose
