440 jetting

[schuie]

I am boring my 400 to a 440 and need to know what jetting to use. I have a WB R4 slip on, a K&N, and am planning on running an open air box, but was wondering the jets for both open and closed.

I also have a stock cam. Do i NEED to switch that, or will that work? And if that helps for jetting. Thanks

Don't waist your money on a 440 kit if you don't change the cam.
What is the elevation where you are at this will make a big in jetting. What comp piston are you going with??

well i gotta rebuild the top end anyways cuz my rings are shot, and i dont have the money right now for a cam. I am gonna run an 11:1 compession piston. THe elevation is around 1000-1200 feet. Thanks
