Belt needed?
I was out doing a timing/carb setup and a question about my drive belts occurred to me.
My car has had the A/C removed, smog pump is gone and recently the power steering was revoved and swapped for a manual setup. Right now there is only one drive belt on the car--for the alternator.
That belt runs around the crank sprocket, water pump and alternator. I have two empty grooves on the remaining pulleys, one on the crank and one on the water pump.
I was wondering wiether it would be a good idea to try and size a belt to go around the pulleys between the water pump and crank as a safety measure in case the alternator belt breaks.
I know there would be no adjustment there, but just having the alternator belt looks just a little iffy.
Thoughts?

Mine came with double pulleys on the w/p and crank and it has a second belt between the w/p and crank. You have to pull the w/p pulley off a little to get the belt on. I do not know the exact belt or length.
And yes I do think it is a good idea to have a second belt, if you throw the alt belt at least you will have the w/p working and there is little chance that belt will throw since you have 50% coverage on both pulleys.

Thought so myself.
It seems some 'Vettes came with a water pump belt and others didn't, according to my AIM. No place around here lists that belt for any '76, '77, or '78 'Vette. I had to measure and then try several.
34.5" worked perfectly for me and my crank/water pump pulleys. That could be a starting point for other folks, I guess.
