help with nos GM fan belts pn #s
 

have an NOS pile of fan belts, think they are from either early 348/409's or early 70's small blocks. PN's are 3953786 and 9433725. If anybody can ID these puppies, would be much appreciated. Selling off a bunch of NOS stuff, incl these. Thx SULLY

If 3953786 is 44" X 3/8,it's a power steering/water pump belt used on 1965 409 equipped passenger series w/o AC as of Oct. 1970.


If 9433725 is 36" X 15/32,it's a later issued power steering belt used on nearly every small block chevrolet as of Oct. 1977.
Cars like 1966 Chevy II w/solid lifter 327.
1968-75 Chevy II~Nova w/350 or 327.
1967-75 Camaro w/327,350 or 302.
1967-75 Passengers series w/327,350.
1971-75 Chevelle~Monte~Elco~St.Wagon w/307,350.
