Thanks - I feel like I'm down on torque even with using the Holley hi-ram. Feels like such a turd down low. I'm thinking about swapping in a different cam to see how much that helps and possibly getting an lsxr intake as well but at the same time I feel like I should just bite the bullet and get a Whipple 4.0 or something to make that big torque bottom end come alive.
My torque converter is set at 3k stall but it's a lot tighter than that, probably 2k to 2200rpm stall in real life so it is a little dirty to drive down low.

Not an expert, but i think you would benefit from a wider duration split, i know my .030 6.0 is a far cry from what youve got, but going from the 222/224 .566/.568 112 to a 219/235 605/585 114+3 made a hellacious difference in low end in my truck.... Actually made a hell of a difference overall.... and that just sotp...

Yeah this cam is a racing cam - my buddy said it would be good for the street with a blower - but it's gonna be a while till I add any boost, if ever.
Thinking about the BTR big cube stage 3 cam - Cam specs are 239/254 .624"/.595" 114+3
