Does anyone have a cam card on a 590 purple shaft. I just bought one from my local dealership and it didn't come with a cam card. I need the spec to dial the cam in.
Thanks for any and all info
Kevin

The specs are usually on the end of the box, but google is your friend...

Specifications: * Advertised duration: 312 intake/312 exhaust * Gross valve lift: .590 in. intake/.590 in. exhaust * Lobe separation: 106 degrees * RPM range: 3400 to 6900 * For super competition applications with manual or automatic transmissions with race converter. * Three-bolt

Depending on the rest of your combo, you will want to put it in between 102 and 106. GREAT cam, I ran 10.27 with one in a stock stroke pump gas 440,iron head 452. 3400lb Dart.

But its not! Its duration is actually 271/272 @ .050 thereabouts,

Reguardless, 265 or 272 install it at between 98* to 102 ICL for best performance in most apps. mike

Some of those spec.s are quite a bit different than what I remember WOW
'
I too have run and am running the .590.
Lots of people say "theres better cams" I`ve just never found one.

Is that really a 114c/l on the 484hyd?
I`m putting a blower on my 383 and was looking for a cam with 112--114 lobe centers ,but it already has a 484 which IS a 114?????
I thought the 484 was 110 c/l?

Should be interesting to see what the .590 does in my upcoming build and the low numerical gears....

Both the 509 and the 484 have been revised(lobe center change to 112 and 114) in the last few years for better "street" manners.As far the 590 goes,you can do better but I know lots of folks that still like the old warhorse.

Here is the card that I got from the Tech line guys. As everyone has said and the new paperwork details the duration at .050 is actually 271. This just gives you the opening and closing points.

312 Mechanical: P4120663
Duration Intake Nominal 312 Duration Exhaust Nominal 312
Duration Intake @ .050 265 Duration Exhaust @ .050 265
Intake Lobe Centerline 104 ATDC Exhaust Lobe Centerline 108 BTDC
Lobe Separation Angle 106 Overlap 100
Intake Opens 52 BTDC Exhaust Opens 84 BBDC
Intake Closes 80 ABDC Exhaust Closes 48 ATDC
Intake Lift .590 Exhaust Lift .590
Note: as installed on 104 centerline per Chrysler

I've posted this before but, this is what I've found on the MP/DC Purple SOLID cams:

Their advertised durations use timing events @ .015"

I typically find, duration @ .020" is 8 less. i.e. 312/590 cam is 304 @ .020"

Duration @ .050" is 32 less than duration @ .020"

So the 312/590 cam looks like this:

304 @ .020"
272 @ .050"

I hope that helps.

In addition to the actual duration at 0.050", this is what Dwayne Porter measured on one a few years ago.

MP .590 cam, actual measurements-
DUR. @
.020=303.5
.050=270.5
.100=235.0
.150=205.0
.200=177.0
.250=148.5
.300=117.0
.350=76.0
lobe lift@TDC @105 ICL=.140
LSA 106

Gus,
I have a feeling the 0.590" cam might like more compression ratio than you have. What is the combustion chamber size on your set of 452 heads? They vary a lot.
