For what it's worth...

My combo

5.9L magnum.
Stock heads
2bbl M1 intake
222/228 107LSA, .544 lift
4000lb truck
Stick shift 3.92 gears, 27" tires, stick shift

2.2-2.3 60'
14.2 @ 99 mph

Your combo has a slightly smaller cam, but better flowing heads. You have a lot more potential with more tuning.
