You’re right, I was probably looking at a different cam when I saw something other than .470 lift. But you can see they still recommend a 3000 stall. I do have a 2500 laying around that I could probably put in but I was hoping to stay stock. Maybe that stall recommendation is for a 400. I bet I’m on the shy side of their 120lb of recommended seat pressure, too. Check out this page from Summit Racing https://www.summitracing.com/parts/sum-2821

I had a shop check my spring rates, combustion chamber volume, etc when they did a valve job and put new guides in but for the life of me I can’t find my notes anywhere. I recently moved and I think it was lost in the shuffle. I know they weren’t quite 120lb though
