He does not mean what your saying.(victory tech papers)cam info.
How can (in my example) a mopar .484 PURPLE SHAFT and a comp XE284H have the save valve events---and the same @ 50 lift measurement--- plus the same advartised duration measurement and be on some other method of duration measurement???????
They are both 284 advertised cams.
241 @ 50 for the mopar cam \\\\ 240 for the comp cam
They are not exactly the same.
The mopar came has a 108 LSA and the comp cam has a 110 LSA.
These cams are being measured at .006 lift.for there valve events.
They are being measured at .050 lift for their duration.
Sometimes you have to look at things from a different angle to see the target.
Take a step back and look at the big pitcher.
I think your jumping to a conclusion, based on reading something from the wrong angle.
If you could explain the way you think mopar rated it's cams differently then just explain it.
I think you misunderstood the tech article.
He means to say, that it is RIGHT to use A @ 50 lift measurement ONLY FOR PERFORMANCE CAMSHAFTS......NOT OEM\STOCK GRINDS.
There are some stock grinds in that article.
This is why he said it.
