So when I bought my duster the PO said he had put in a cam kit that included a mopar purple... 'One size bigger than the smallest they had'. All my research is turning up that mopar only offers 3 cams for the slant six these days. This may have been about 3 years ago. All 3 of mopar's offerings of mechanical purple stick cams for the slant are way too big to put into a car that has probably a 2.76 gear, stock converter, and stock size tires. When it ran I didn't notice any major idle loping. Any idea what this guy might have been talking about? I don't think he had any reason to lie. I might just have to caliper the lift of the valve retainer to find out what's in this girl.

Probably this one:

P3690766 SS14-112 268° duration .450" lift, 108° LSA .016"/.020" int/exh lash

I'd say that's a pretty good street cam in a 9:1 motor.

And a little more rear gear would make it fun. There is a guy here in Salem that built a 10:1 slant with that cam/4-barrel and headers for his A-100 Van...He ended up breaking a couple of A-727's hauling rolls of carpet in it (it was his work van...)...LOL

-D.Idiot

Yeah I ran the numbers through DD and it seems like it should do pretty well.

That cam will work well IF you combine it with more compression...
That cam does not work well if you use it in a stock compression engine. (8 to 1 or less is usually where a stock slant's static CR is)
DD

what compression & carb combination would suit this cam? the cam that pops up most while i'm searching is the comp cams 440/440 solid & is what my friend used. but i want to go a bit faster than him
