wow that sucks, I too went from TSP cam to cam motion mine is sub .600 lift. I had .660 lift txspeed valve springs but have since gone to much lighter springs for a LS that I have to shim in. Forget the specs now, I'll go look for them, I lowered the fuel cut from 7350 RPM to 6900 RPM. My cam looks good at 20K miles and 6 years. I hope I get 20K before I look at it again. I feel good that I went to a much lighter spring and lower fuel cut.
FWI GM has a NA cam for there L8P 218 /231 .549 lift on 121 LSA. which I would do if I have any issues with my current cam motion.
I thought this was interesting, they have a whipped out cam the blame the oil and sell the customer an even bigger cam.
