    Stock engine you don't really want to drop pulleys unless you are getting 0* KR Then you could drop down to a 3.6 but you'll likely knock quite a bit on it.

    after seeing people ask this so many times im just going to say you should be safe dropping to 2.8 on a stock car, as long as the pulley fits who cares LOL

    I think 2.8 actually wont fit, doesnt the snout of the blower have to be machined to work a 2.8?

    Machining necessary for anything below 2.8

    Machining the snout is required anything below 2.7

    im pretty confident on that.

    So i say, machine the snout, run a 2.55 on a stock car.
