If you use the 83.5 inch belt you don't need the smog pump delete, but you just have to change belt routing a little. I think someone on here had a belt routing diagram that they could post. It pretty simple to do, you could probably figure it out once you look at it
Thanks for the info. I used this size belt because w/o the smog, it should be 6 inches shorter. I had an 89.5 inch belt on the car (ASP Overdrive alternator pulley needed a 1 inch shorter belt) Factory size being 90.5, I took off the inch for my "stock size" belt, then 6 more and came up with your 83.5 Works perfect. No more pumping sound from the smog pump. I hated it!
I would either buy what you think you'll need and two sizes bigger and smaller, or do the swap in the parking lot of the parts store. It just seems that each car needs a different belt, give or take a 1/2" or so (sometimes more). It sucks to make an all-day project out of a 5 minute swap (having to drive to the parts store 10 times).
WTF?? lol i have all accesories, and deleted my smog and i could have SWORN the only belt that fit was a 71.5'' belt. and no you dont need the smog delete, you are still spinning the waterpump the correct way.
