Alright,
Here it is: I have a '77 300 motor in need of a rebuild and rather than tearing apart my '85 that is running, will the '77 head bolt up to the '85 block? Also which is the better flowing one as I already have the Clifford intake/exhaust pieces on the '85 and really want to know if they will interchange or which would be the performance choice. One more thing-were the cranks of the circa 80's models the same as long as they were in a light duty van or truck?
Thanks for the help.
