I'm ordering a ford racing a/c eliminator kit. I know the belt length is 73" with bypassing the smog pump. I have under drive pullies so do I go 1" shorter?

I would save the money . Instead of getting the a/c delete pully you can go to shorter belt to bypass the smog and a/c . With underdrive pullys you can take a piece of string and route it the way the belt would be then messure the string. Aslo most places like autozone will let you try belts on at the store till you find the right size.
here is a pretty good guide for routing but remember with under drive pulleys size will vary .

The a/c delete kit is nice, it moves the power steering pump up to where the a/c unit is located. The kit is basically the brackets that come on non a/c cars.

As for belt length, get everything put together and then as mentioned use a piece of string, but make sure to move the tensioner up a bit to simulate the belt being there.
