BIG BLOCK MAX IV ENGINE MOUNTS. so i had this issue with the drive belt making noise and i was loosing grip on the belt when pulling hills. so after taking a vid of what was going on i found that the engine was pulling down and the engine twisting when under heavy torque loads. so after watching the vid a few times and looking at other types of mounts i came up with this. theirs not much room to work with so i had no choice but to double up the mounts and do some welding. could not go any larger in diam.
