LD 340 vs Performer RPM?

I switched from a factory 360 TQ intake to a standard Eddy RPM on my 318 (360 heads) it made a world of difference in mid rpm torque and pull. Upper rpm range was also dramatically increased. Seemed to pull to 6k way more quickly.

All seat of the pants dyno. Volare RR street car, mild cam, headers, 2.5 duals / 3.91s / a833 od.
