Right, I was planning to use side mounts. What I wanted to know was whether or not the side mounts that are already there will work with a small block. Since the 6 was a later model and used side mounts, the same as if you had a 6 in a Chevelle or Camaro etc., can you use the 6 cylinder mounts to install the small block if you have the right rubber motor mounts? Or, do you have to replace the chassis mounts in cars like that to replace a 6 with a small block?
Because if I could keep the same chassis mounts in those cars with a 6 and just get the right rubber mounts for the block, then I should be able to do the same thing in my '57.
