I am trying to fit a 318 engine into a 35 plymouth. It was in the car when I got it several years ago but it needs to be repositioned to work correctly. Can someone tell me how many different motor mounts were used on the small blocks. I have to make new frame mounts and thought maybe there is a mount that might work better. The ones I have now use a single long bolt that goes through the mount and frame brackets. Is there a motor mount that has a single stud that goes into the frame bracket? It may be easier to fab some frame brackets that use a single stud. If there is, what kind of vehicle used them.

 

You could try a frame mount from a 70s pickup…

 

Are you looking for something like these?

Which 318 are you trying to fit? There was the wide block "poly engine" and the newer 318 LA produced after 64. The mounts are very different.

 

Thanks for the response. This is an LA engine. The mounts on the Mancini site may be just what I need. Fabricating brackets to fit those should work out better. I will have look at the 70's truck mounts to see how those will work.

 

I bought a 40 plymouth with a 340 already installed. If you are using an updated rear remember to offset the engine to match the input shaft on your rear so you don't have an unfixable vibration.
