Have to agree with that statement.

The Mickey Thompson Crossram for the early engines, (even with the balance tube added), looked cool but did not perform anywhere close to the later 4BBL intakes from Edelbrock and other sources. Skip Fix has posted about this too.

divide that dimension by 2.

4) Make your stuffer blocks so that the bottom of the stuffer blocks blend with the Head Port Opening.

5) Make the top of the stuffer blocks so that the runners have the same dimension for the runner (Left to right) at the top is the same as the bottom of the intake runner.

Drill holes so that you can tap and screw retention bolts thru the outside of the runners into the stuffer blocks. That keeps the screws away for your engine parts.

Not a thing wrong with Larry's Gutsram. Just needs to be "Runner VOLUME Tuned" for the application.

Thank you Tom.
