yep 360 bolts right in with the correct balance TC or flywheel.

everything from the 318 can be used sept for the oil pan. that would need to be a 360 rear sump.

maybe a few washers on driver side motormount bolt to shim it up some.

talk with the JY,tell them you want a good runner and that you are at least re-gasketing.

leave the long block together and replace gaskets. look in the springs and see if it would need the valve seals replaced.

shoot for a newer engine so it comes with a roller cam block.
