A couple of my customers have asked that I add more big duration and lift profiles for the LS1.
I'm just trying to find out how big to go.

Right now, the biggest .050" duration for a LS1 Hydraulic Roller profile I have is 250.
The tallest lift profile I currently have is .637" with 1.7rr.

I'm also in the process of designing some lower lobe lift(.330"-350"), big duration(242-255@.050") profiles to work with the Z06 1.85 rocker ratio.

What are the biggest cams you guys are running right now?

 

mine is a 246 248 @.050 .615
I have seen a few in the high 260's
