Newbe with a cracked block.

biggest problem doing a v8 swap is getting the v8 push button trans.. after that its cake...

motor mounts you can buy new if ya can't find used ones..
exhaust manifolds pop up all the time for early abodies
v8 center links pop up on a regular basis too..

if you are pulling the engine then go v8.. nothing more boring to drive then that stinking slant six...
