Randy,
When I first got my LSC the radiator was laid back alot.Forget the angle now but I believe it was right at 40*.
I moved it to 30* and did notice a difference with the 392w.
I was over at Don Barnes shop well before you bought your Cobra from him.I commented to him that he really needed to move it up.I guess he didn't.
How many degrees did you get it to ???
