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

i thought it was 2.7 or lower but i could be wrong, so lets say a 3.0 on a stock car LOL

 

[DanPrixGTP]

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.

or maybe twin charge at 25 psi from turbo on a stock car, maybe change plugs all will be well
