I would love to see it ground on a 112, that would change the overlap ot -9* which would have tons of low/midrange....

How would the curve change if it was in a 6.0??? would it lower the peak power down in the rpm range?

I would imagine it would shift the entire curve down in RPM for sure. IMO this cam is too small for a 6.0L motor to make it a worthwhile swap.

The thought was to use this cam in a towing/weekend truck. i recently got a company truck for work so mine is now a toy hauler only. Wanted to gain down low, i tow right at 1900 rpm on the highway

Nick I have similar cam in my truck when was n/a and I like it lot. I ran 14.6 with 2500 stall with that cam. I'm running same cam with my turbo set-up. I'm glad you like it.

I just installed the high lift version of this cam on Saturday. It idles with a little rumble. It pulls really good but I need a retune also.
