thank u arthursc2 looked into it and seems like thats the one. apreciate it boss

 

That cam is not a direct cam only swap - You'll need new valve springs for that cam and recommend a trunion kit for the rockers as well. Might as well get LS7 lifters and some decent pushrods while you're at it too.

 

yeah thats what the performance shop told me.. apreciate ya'lls help guys.

 

They make a low lift version too, but I haven't heard of anyone having issues with pac 1218 springs and that cam
