Roller LA cam in a Magnum?

True story...it does work but as kuda said-it requires machining to perform it's function (don't ask me why they don't sell it machined to begin with...I already asked Hughes on the phone and they couldn't provide a legitimate answer). IIRC, my machinist took 0.105" off the open end of the cup washer and it all mated together satisfactorily.

). I had to rework their "adapter kit" as I wasn't comfortable with the way that they designed it.

Yeah...I'm pretty sure they did that on purpose...and like I said above, no idea why.

If I were to do it again, I'd just either buy a custom LA roller cam like Walker did, or have a stock LA cam reground by Oregon.
