Al, try this site. http://www.gastanks.com/1970/products/531/ It is Quanta restoration and they make beautiful reproductions of belts for most GM cars complete with the part number and GM stampings.

But the 44 inch belt will only fit a 350 LT-1 that does not have the A.I.R. smog pump. Benn there and tried it with a 44 inch belt. The books need to be revised for the correct belt which should be either 46 1/2 or 47 inches long. Thanks for the comment.

Closest thing is see is 539130. Thats a 47.5 inch belt

3937790 is a 45.5 inch belt

These are all of of my GM parts book dated 1977.
The above belts are Nova and Camaro 396.

I think that the books just don't address the right belt for this car. It is probably listed as the belt for a '68 or '69 Camaro with this engine setup. I have measured around all the pulleys and it has to be something less than a 47 inch belt but 44 inches is way too short. At 47 inches, the alternator is adjusted at full tension bolt position and 44 inches will only fit around the fan and water pump, won't even come close to going around the smog pump pulley too.
