better engine mounts or torque strap

Cheapest and works for me, 2 bolts and a chain.

^^^^ Xs2

Rubber biscuits, $3 worth of chain, 2 bolts, held down a wheelstanding hemi for a coupla decades.. still does.. lol

Chains just loose enuff not to transfer engine vibration, wrapped in black tape so it doesn't rattle..

Schumaker re-inventing the chain and charging a fortune .
