I bought a 350 with a th400 attached. Due to the amount of changes needed for the nova I'm stickin with the PG. My question is I'm tryin to remove the tranny from the 350..and I've got most of the bolts out..is there a trick to separating the two when I take out the last bolts? (a quick convice with a 2x4..rubber mallett, iron bar!) Also ... is there a gasket or material that will go between the new engine and tranny...or do I just bolt them together with clean joints on each.
