If I did my motor again I would plop in the 2.9 instead of the 2.8.
I have a fast road cam in mine from burton. works well from what I can tell, but I never drove it before I pulled the motor (spun bearing).
Mine makes a tapping noise no matter how many times I adjust the valves. maybe its just the cam... but I am not sure.
the rockers are worn .. but not that bad so I am not sure if it is them either.
runs good though picks up nice in the high rpm's.
