hey all. I found 3.91 gears on ebay 11/43 tooth . I talked to the owner of the company and he said when theyre gone theyre gone. US gear makes these so be your own judge. I bought a set this week.
hey . I just put an offenhauser 360 single plane with 750 dp mech secondaries under ram air hood. Runs awesome. Its a lot better than the 4300 carb and stock intake.
