CAT Gear Drives

I agree with Moper on the chain set and the MP tensioner. A buddy put one of the gear sets in his 56 Chebbie, and turned a nice sounding engine into a noisy, rattling, sick-sounding POS. I don't believe it was a CAT set, but it was one of the well priced, but still expensive, units. That thing stayed in for one summer before being replaced with a Cloyes chain set, and the engine sounds like it should again. Just my $0.02.
