so, i had VNV over to help me size the v belts for the water pump and the alternator....the short version is that i am using an "idler" belt to drive the double water pump pulley off of the crank pulley...i then use a single belt off of the water pump pulley to drive the alternator because the header based alternator bracket is so low that a single belt will dig into the lowere radiator hose...two belts eliminates that problem....
so, we must have done eleven runs to advance auto parts for various sized belts and VNV comes up with a logical idea for the idler pulley which is the major problem....let's log onto their website and get the correct part number for the idler pulley (all the while i'm thinking that having a correct part numer has NEVER work for me with belts....i order 3 up and 3 down from my guesstimate and just return whatever's left over...of course, i have about $600 of v belts on my credit card at any given point on time but it works for me)
...so, we get the correct idler belt number for a '65 sb corvette, no AC and guess what?.......it's about 3 feet toooooooooooooo long...ANOTHER trip to the store
finally got the belts by my usual method of +3/-3
only me

..we briefly thought of calling 1.800.JOHNZ for advice but it was just easier to go back to advance and talk to the counterman that had NO clue.....i got to the point where i would walk in and go to back where they keep the belts and just started measuring.......
