I have a Mopar Performance purple shaft cam .533 lift 272@.050 duration. I know little about this cam. Idle? RPM range? How Much compression does it want?

I'd guess you'd want 10.5:1, 3800 stall and at least 4.10's.

Ive got a 413 punched out to a 426 with eddy heads. I estimate 10.6 to 11 to 1 compression. I got the car as roller and the 60, ss spring and ladders were already installed. Cant wait to get it running.

i've used every cam the mothership makes with great success (yes! do not try to dissuade me!), except that one. i am VERY curious about that cam. huge duration and not much lift- sure would be easy on the valvetrain in an endurance application.

As best I can tell Mopar originally set it up to be a close competitor with the older Comp Cams drag hydraulic, the one with .540 lift and around 265 @ .050. The two cams are close enough to where they probably run about the same.

It's never been a big seller and because of that it was discontinued recently.

I've never used it personally and can't vouch for how it works.....but have talked to a few who loved the cam and seemed to be bummed out it was discontinued. One guy said he loved it in his 4.88 geared 383 4 speed car....

I used one for years 4000 to 6200 with iron heads.
I had a 4000 stall that flashed 4200
I would degree it in at 102 on a 413 and have at least a 4000 stall 4500 to 5000 may be better for drag racing
Makes good power real good

How much different of an idle does this one have compared to a 509?

I went from a 509 to it and it was not that much different but I like 1150 in gear and the 4000 stall. mech advance only 38 all in by 1250
defently put it in at 102 (even 100 0r 101)

2 degrees advanced would be 106 on that one (108 lsa).
