Pick a cam for me

rumble fais to remember that I did not list race grinds
Lunati chevy voodoo and mopar voodoo are exactly the same as far as "agressivness" goes
but if you want less than the street mopar lobes I listed get MP, some Crower, Some Engle
they will still give you more butt dyno than the 50 year old grinds- the old ancidotal favorites

here we have a couple of challanges
fist do the detective wor for asingle spring to replace duals, maybe beehives
a call to the tech line or spring list should do it

split cams
really depends on exhaust flows, manifold, headers, heads not as simple as it used to be

273
pick your intake duration- here we have very low compression , a not too high stall converter and 3.55 gears
and check against the rev range you are looking for 3.91 in a dart would be different
really depends on how and where you drive it stop and go, speed bumps , or wide open highway where you can give up some bottom end

That's all well and good, but what does the OP want a cam that take his 250 hp ish engine to 300 hp ish, not a huge of a request, any cam stated so far will accomplish his goals and more, if you think you know of a better one state it.

I get for a lot of high hp and or complicated requirements science the **** out of it, but this one and a few of the last threads on this, it ain't all that complicated, I'm pretty sure Chrysler science the **** out of the factory cam before they decided on it, not saying there isn't better choices.
