This car is a big lumbering highway cruiser. It needs power between 2200 and 4500 rpm.
The recently deceased cam was a Comp 21-000-5 single pattern cam. 261 degrees (218 @ .050) and .463 lift with 114 degrees of separation.

It might have been a slight improvement over stock but it was still a gutless pig.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
