Zzylstra's did worked perfectly like he mentioned. Mine on the other hand, even with 2 blocks and straps, popped off In 2 days. My alignment was off a tad and the screw type clamps on manifold side backed off completely once prior to it completely popping off. My engine vibrates more than normal and is able too loosen and unscrew hose clamps. Perfect alignment & T-bolt clamps is the ticket on mine.
