Any help would be appreciated.
Its easy to break a case. Cheap cast aluminum pot metal. If the engine mounts are off kilter, or excessive chassis flex. Or if you bolt the case down and use the bolts to "bring it in". Engine has to sit perfectly flat and easy, before you can bolt it down.
Maybe one day, we'll have billet blocks...........
