Hey Bongo,that is probably a good idea you have. The small block Chevy engines are very popular for a number of reasons. Mainly because they can be bought cheap,are easy to work on,and parts are readily available for them. As for motor mounts,I am very fortunate to live close to the main Summit racing store,about 80 miles from me, and a very good hot rod shop closer than that.Just about any conversion is possible with todays engines.When I installed a 350 in my 55 I bought a motor mount setup from Brothers and it fit right in.Pick up a performance truck mag.and look thru it,then order catalogs from the various aftermarket suppliers.I am sure you will find what you are looking for.
