Take a look at the Lunatti 703 cam. Depending on your compression ratio (10:1) it would be worth a look. You might also want to increase your converter stall (3000-3500) JMO 440'

The dual plane intake may rob you of some high end power judging by the build numbers posted here.

Good luck. The ld340 has been around forever, and is a great street manifold.
