I stopped using the original front engine mount studs years ago and use 3/8" BSF bolts. I nip them down but don't whack up tight and, at the rear, use an old clutch spring under the chassis rail to the near side engine mount. This on both solid and rubber mounted crankcases. My old Trials Car did 25 or so years of trialling like this without any problems
