"Fully Modified" Cast Iron Small Block Chevy Intake Manifolds

Our Fully Modified intakes are more extensively ported Stage 1 manifolds. They are the most powerful cast iron intakes available anywhere. Fully modified intakes have a modified plenum area, are port matched, and modified through four access port areas. 100% of internal area is modified. This is the most extensively modified cast iron intake available. Compare for yourself with the dyno tests.

Also, they maintain an absolutely stock external appearance with original casting numbers intact. What this means to you is that from the outside no one will ever know you have a modified intake.

"If you are running Hobby Stock, Limited Late Model, or Sportsman, you couldn't miss hearing about Brzezinski because he is the prime exponent of having the stock cast iron intakes and heads pull more air than ever before. He has learned all the good part numbers and the ways to make them respond."
