Cam upgrade for my truck, '72 D200 with a 360

That is a good grind for your application if you can find it in stock anywhere at the present. What is your cranking compression at the present?
Personally, I would look into running this setup based on my present experiences with a cam upgrade in a very heavy truck with a low compression 360.
