Motor mounts?

Yes, you will need new mounts, the drivers side is different! But if you have two passanger side mounts from a 318 it will work, my father has a 67 Cuda that had a 318 in it and thats what I used to put a 340 in it!! Shumacker has mounts that you can buy, but the 318 mounts are a hole lot cheaper! hope this helps! :salut:
