I'm no expert on cam grinds, but what I see is large cubic inch(540+) and or high compression and or nitrous combos handle the wide lobe sep much better than low compression and smaller cubic inch motors. Mine was a 408 10.5:1 and the vert was a 3500 at the time. It hated that 112lda cam. I'm sure some may have had good results, but me, MR.P, and Don didn't and I used to see a lot of those for resale 10yrs or so ago. I'm glad yours is working good thou, that's cool.
