A cam that small won't give up low end especially on a 112. I've got that cam's big brother in my 6.0 (232/234 .595/.598 112+4) and its got a fat bottom end. I'll have numbers to back up that statement next week.

Agreed though, springs are NECESSARY, and you're not going to like how it drives without a stall. In my 5.3 cam selection I'm looking seriously at a reverse split.
