Assume someone is running this set up and can save me some time by telling me what belt you are running.

6.0 with ati 10% UD crank pulley and katech solid tensioner. Stock PS and ALT. Thanks

Wow would have thought someone was running this set up. How well I'll have to measure.

I guess nobody knew what a "blet" was. I had to look it up.


(Plant Pathology) a state of softness or decay in certain fruits, such as the medlar, brought about by over ripening.

You seriously didn't know what a blet was, geez such a common thing in racing.

Oh well time to move to a group more educated in fruits.

What engine are you running? I would imagine LS6 vs LS7 might use different belts. If you are running an LS1/LS6, you should also know that underdrive crank pulleys have been associated with timing chain failures in the past, and so people into road racing/track days tend to avoid them.

Also, you might get more interest if you change "blet" in the thread title to "belt".

If you have to measure, be sure that what you end up with allows adequate movement of the tensioner. If you run it too "tight" it can have some ugly consequences. BTDT

I have had to install unknown belts many times. What I do is run a tape measure as I would a belt and get my best estimate as to the length I need. Go to the parts store and take a look at the belts. It takes just a moment to decipher the part numbers and translate them into lengths. For example: 775k6=77.5" 6 rib. I then buy 3-4 belts and try them out. Return what does not work.

me as well but thanks for the tips. I was just hoping to avoid the steps.

Hey Edge - so above message means you figured out your 'blet' size? LOL, you were a good sport about it above

I have a brand new GM / Pace Perf LS2/3/7 corvette accessory drive in a box. Belt label says pn 12636226, 6 rib by 2025mm.

Hope this helps!
