higher ratio rockers on gt2-5 cam? higher ratio rockers on gt2-5 cam?
I was just reading this link http://www.ls2.com/forums/showthrea...7646#post327646
(needs to be a permanent sticky very good info)
and I found the difference between my lift at .006 and .050 is 53 a number which seems to be right in the middle, denoting not an aggressive lift cam (xer grind) nor a mild lift cam (xe grind). This is a lingenfelter gt2-5 cam.
The heads have a larger 2.00 intake valve and .050 milled-going in 5.3
My question for all you guru's is with this setup can I run higher ratio rockers like 1.8 or 1.85? I know the xer grinds you arent supposed to but this cam is right in the middle with the higher ratio and higher lift would I run into clearance problems?

Ok judging from the cam specs on lpe.com GT2-5 222/222 .566/.566 112
those lift numbers are at 1.7 ratio if you went with some 1.8's it would put your new lift at .599. The lift would be fine with some really good springs. It looks like the ramp rates of the cam would be ok with the higher lift rockers too. In my opinion you would be fine running that setup but i'd clay it for PtoV clearance to be on the safe side because of the new heads.
