I know these cam questions are like a dead horse.....
I'm building the Dino 4.6 budget stroker and it's cam time. 7120 head stock other than a fresh rebuild and a 3 pt valve job. I don't need it to be a screamer but I do want the best that I can get for it's build. It's bored 20 over and has the usual 12 wt crank/677 sealed power pistons/258 rods. It will be a daily driver and a weekend rockcrawler and I expect longevity. I was leaning towards a Crane CRN-753905... Any inputs?

Re: Good cam for stock valves/springs
You are going to be limited by spring bind. If I am can remember correctly, the stock valve springs bind at .450 lift. Have your machinist check your spring bind.

Re: Good cam for stock valves/springs
The stock valve springs are rated to to 0.430" of valve lift so choose your cam accordingly from my spreadsheet:

Re: Good cam for stock valves/springs
I'll be going with the Mopar P4529228AB Cam since it's right on the .430 mark for valve lift. Should go great with stock springs yet give me a little more performance with my mildly built stroker. I came into the stroker build with high hp/tq pipe dreams and after numerous reads, I more and more find myself deciding to play it safe and mellow with a super fresh rebuild and mild tweaks. To many people are blowing cams and bearings and having issues. I wanna do this once and be done. I remember my jeep new was plenty fast and that only years of play/abuse has caused her to poop out a bit.
