Should I run an air cleaner at the track?

The reason I am asking is that I am going from a torker II to a victor jr intake and I don't think I can get a 4 inch air cleaner under the hood. The hood I have now is a 4" cowl.

Are you using a drop base with your air cleaner?
If not, you can get up to a 1 1/4 inch drop base...then you shouldn't have a problem with the hood clearence on a 4 inch cowl. They are available from various speed shops.
Good luck
