cam for 2 barrel short oval??

You'll never break a cast Mopar crank at 7300...

Cam King spec'd a cam for my sbm (dirt late model) that's really not far off from what you have now... His stuff often specs pretty low compared to what you might expect.

My deal is a 4.030 x 3.79 with a ported set of W2's expected to run about 7200...

How many laps do you get from a cast 4" crank? I've seen a few break in mild bracket cars that never saw 7300 rpm , but if you have on track experience that would be cool. I'm sure Mike could come up with a good cam for this combo.

Well I'll refine my answer a bit...since the 4" arm is likely an import aftermarket deal I'd keep it under 6500. A stock Mopar crank is hard to break unless you really try... The others I'm not so sure about.

What do the heads in ported form flow now Intake and Exh wise, as you really need that info for a Cam pick!
These iron heads do like 245 intake cfm @ 28" out of the box .

He said stock W2's so your number should be pretty accurate.

My heads have a nice port job and flow 280-ish according to the original builder... I've been told a competition port will beat 300 with enough lift but it sounds like his rules won't allow that.

Some of the guys over on Moparchat seem to think the 4" crank is a but much for longevity but I've never run one.
