I am looking for new engine mounts for my 340 LA stroker motor, coming soon. Based on other threads, most people go with the Schumacher PolyLoc but their website shows out of stock for sometime. In an older thread, one member mentioned Mitymounts from Dynatech Engineering. It looks like they have a locking mechanism when motor mount is in tension, similar but not the same as Schumacher. Cost wise is cheaper as well. Are there any members using this mount? Any feedbacks?
