A CompCams rep told a friend that he should replace his belt every year, but that seems a bit excessive. His belt had broken on his SBC 429 after about 3 years and the spider gear was well worn, so he is now wanting to change every year.

Thanks for your inputs,

Look at it this way, the Nextel cup guys run them for 500 miles at a time with no problems.we run them at least that far on our super late models and have never had a broken belt.some of the early belts were only 20mm and we did see a few failures but after they went to a 25mm belt we haven't seen any breakage.Bill

Bill, thanks again for the advice. That was along the lines that I was thinking (at least 500miles).

Sorry guy I don't get to this forum often enough.
A chain or belt is the way to go.
For the money a good chain is hard to beat.
If the budget allows I like the CV Products Belt drive.
