PUZZLER!!! My new motors a dog! what did I miss?

rebuilt 360
KB107s
J-heads /2.02s / bowls cleaned up and blended / good springs / Hughes rollers / Smith Bros pushrods
Lunati 262 cam (voodoo) Checked the degree on install
MP Electronic ignition (orange box) / new jacobs coil
Dougs 452 Headers
LD 340
Eddie 1405 ( Have used a 3310 750 and 650 DP as well)
Timing 36 total/ 20 initial (have tried various combos)
checked reluctor phasing
15-16" vacuum at idle
Cylinder pressure 140-150 ... ( a little weak..)

Engine idles at 750-800 sounds fine
Drives smooth

Runs like a decent /6 ! with a lot of rumble... wont even spin the 3.55's and P205/70r14s.
doesnt seem to want to rev past 4500... yet cruises real nice down the hiway.

plugs look lean no matter what jets and rods I throw at it ! Finally went to .107s and smallish rods just to get some color showing ! Way rich now ..Eye burner !

The machine shop installed cam with both dots at 12;00 so I checked it out and unless I screwed up it was dead on...which surprised me !!
But it shouldn't run decent if that was the case....would it ?

I want some input before I tear this thing apart again !


Go for it GURU's !! What's your take ?
