Nick, as you know, I run the Lunati 60303 cam

440 .030 over
Oob Stealth heads
.017 below deck, Cometic .027 gaskets for quench
10.2 Compression ratio
Eddy RPM
Holley 850 DP
Headers

833 4 speed, 3.55 gears, 28 inch tires.

Cam was degreed, came in at 106.75. (Was supposed to be 106). I ran it that way for a year or so then advanced 2 degrees to 104.75-----I was bored, don't get too caught up in this detail.

I can pull away from a stop at 1000-1500 rpm as long as I'm light on the throttle until 1900 rpm, then full throttle is OK (and of course will fry the tires).

What I CANT do is pull away from a stop at less than 1900 under moderate or heavy throttle----if I do the engine will lug.
It's all about split second timing of the clutch vs throttle--that's all.

Similarly, I can cruise in 3 or 4th gear at 1500rpm, as long as throttle is LIGHT--if I want to accelerate from this condition I either stay gentle till 1900, or downshift.
