Man, I would love to get a GM 60Degree 3.1 or 3.4 V6 in my 1984 Cherokee. Her 257,190 mile 2.8 just keeps goin, despite her current 28,?++ mile OCI of various ND30s going through her SuperTech(Vitnage 2007)3387A oil filter. Im sure this filter has been in complete Bypass mode since around 7,000miles(Fall2007), or so.
