This one will get you full judging points. It was used on the 1957 and 1958 Corvette with dual 4 BBL carbs, the 1965 Corvette 327/350 with power steering and w/o factory a/c, and I believe it was also used on the 409 dual quad engines in the full size Impala. The original part # for this pulley was 3713974 and was later changed to 3827846. Check my other auctions for some nice used and NOS parts.
