Belt size for smog and ac bypass

[rdharper02]

I want to bypass the ac. The smog has already been bypassed. Anyone know what belt size I need?

You can't really bypass the A/C, the belt will rub on the water pump. You'll need the FOrd Racing A/C delete kit to lift the power steering pump up high enough for the belt to clear properly

No worries, I will look into it.

i ended up with about three different belts, with the AC delete from ford before i got the right one. I want to say its 72.0 inches that i ended up wiht, and thats with UD pullies

There's no reason whatsoever to bypass the a/c unless you remove it all together. When it's not operating it's just an idler pulley and does not rob any power. Your only benefit would be completely removing all a/c components for the weight savings, but there are no power gains to be had.

my a/c is completely removed, smog pump bypassed, with u/d's. i JUST put a new belt on my car and 72 should work nicely, i bought the wrong size before actually checking and after i measured, i went with a 72.5, but a 72 would also work. and dont be thrown off by u/d's, i could use my previous belt w/ my underdrives because the bigger crank pulley makes up for the reduction in the size of the alternator and water pump pulleys...not sure if that's the case all the time though

It could be a slight tighter but works ok
