This question comes up a bit on how to identify a pulley, probably will more and more as modified cars end up on the used circuit. These diameters I measured "peak to peak" on the metal ribs where the belt rides.
Stock '89 - '93 => 3 1/8"
Stock '94 - '95 => 3 1/4"
March 10% ====> 2 7/8"
Magnusen reports and John Shelton agreed with the following.
Magnusen standard "S-Port" => 3.135" (3 1/8" same as stock '89)
Ford SVO (5%) ~ 3" (Magnusen says 2.935" John measured 3")
There are more pulleys out there, I am not sure of those diameters anyone have them? I am specifically thinking of the S&S enterprises pulley that was advertised a lot in the early '90's with the "Soaring Spirit" T-bird book. I think Superchips supplies a pulley with thier chip, not sure of that diameter either. ASP?
