MP .474 purple cam

What I"m interested to find out is if you have a mopar 238 deg @.050 and a cam from another manufacturer with 238 deg @.050 will they be similar behaving cams.

I think not, Mopar even says that you can only use their Duration at .050 to compare mopar cams and that its not accurate to compare to other brands. I'm guessing because its a mathematic formula to get their duration numbers rather than actually measuring them.

Guys seem to be running much faster with say a comp 280H/ 230 deg .050 than a mopar cam .474 238 deg @.050.

It goes back to them making the statement that their .474/ 238 @ .050 cam can be run effectivly with a stock convertor when another manufacturer claims that a cam with 8 degrees less duration needs a 2500 RPM stall.
Everything else being equal the mopar cam should need a 2800 RPM stall.

Something is fishy with their duration numbers.
