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.

I ran the Voodoo cam with the same advertised duration as this it's basically one "step" above the smallest which is the one I linked. That was first in a tired 1970 318 which was the original engine in my Duster then in a 10.5:1 360 Magnum in the same car, bad combo in the latter case gave too much cylinder pressure (pinged a lot/ran hot when pushed). One important consideration is that I'm at 5000' elevation so cylinder pressure is a luxury, so to speak. I did check the cranking compression a while back but I don't remember the numbers I'll have to do it again.

What was the performance change like in your truck when you changed to that Comp cam? Would you say there's any benefit to the stock cam or was it pretty much an improvement across the board?
