Aluminum Intakes - What are You Running?

Yes this is true if the majority use of the car is drag racing. There are even specific directions for the modification in the Direct Connection Engine book. For a street car this would be a bad idea. The high RPM gains come at the expense of low and mid range torque which, IMHO, is where a fun to drive street car gets its seat of the pants feel. This mod basically turns the manifold into a single plane manifold.

Having this intake modded as per the DC book suggests, it worked very well even with a small cam. Any loss of torque was not noticed by the young punk (ME - LOL) driving it at the time. It did provide more power top end NO DOUBT! The TQ was also really helpful in this area.

The DC/MP book said it was the best modification for cams over .600. Which back in the day you read between the lines and re entered. Big *** cam.
