Cracked, that crazy trio on Engine Masters showed that of which we already know from days gone past but tend to forget due to time and age. Velocity stacks have always worked.

When it comes to a regular traditional air cleaner set up, I have always run a flat base with as much filter height as I could get. 4 inch in height if I could. Hole in the hood was always OK. If not needed with a Holley Strip Dom, 1 inch spacer set up. Tops were solid until K&N came out with that flow through top which went on top right quick to my bennifit.

The hardest thing always was good clearance. Everybody wants a bitchin big filter under the hood.
