Aluminum Intakes - What are You Running?

The best thing to do to a LD 340 for maximum performance is well known with the divider milled and the ports opened up, IF you want to run that route on that intake. I also ran a TQ on mine since it was purchased modified like that. It was a beast of a dual plane. One day I’d like to find another one in good condition already modified. A couple of fellas here have run low 11’s with a RPM. The LD-340 is right behind it.

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.
