I just converted my car over to a 12 rib set up and added the ASSC support brackets to my car so the lowest idler pulley by the crank is now deleted from the set up. Running a string line around the crank and blower pulley shows that I need a 62 inch belt however I can't seem to find one anywhere in that size. Only 64 or 61 inch belts. Anybody else here that has done this conversion, what belt are you using? Thanks.

 

how much room is on the adjuster? cant squeeze a 61 on with the adjuster all the way in?i'm going cogs motor isnt in the car yet

 

Im not using the procharger tensioner. I've added a spring loaded tensioner.

 

Pardon this being my first post here. Not new to Camaro world or Prochargers. Ive ran 2 cog setups on the street. Very loud and the ATI overrun clutch is mandatory with a stick and a very good idea regardless. Cog belts have no absorption with rapid throttle closings. A DD will eat belts rapidly.

For the OP you can get the 61 on. Back the adjuster all the way. Get it started as far as possible on the head unit pulley. Bar the engine over by hand to install the rest of the way. Heres the Gates page for a 62.08 belt just in case.
