Can someone help me with this CAM

[Sixt8Chrgr]

I have the following camshaft in my 69 R/T and it just does not work well with my setup. Basically I have a stock car and when I put the car in drive I have a 300 -400 rpm drop. The car also just does not have the low end torque I prefer. However, once the rpm is about 3000 the car comes to life. I want to change this cam out to something more streetable stock cam, but don't know the specs of the cam in the car and want this for reference.  The cam in the car is a purple shaft part number 762290. Anyone know the specs? Can't find the specs on the internet.

Thanks!!

Before a recommendation can be made, people need to know your setup. What gears, carb, and exhaust are you using? Auto or standard?  Is everything stock? Heads, compression, etc?

WHAT Part # ?

I can't find anything "762290" either ?  Where did you get that number from ?

Moving forward,
a good NEW Cam Rec doesn't require the old Cam specs. Consider it a "nice to know", but it matters not.

What Cam guys really need to know are things like:
* What Engine, 318/383,440 ?
* Rear End Gear Ratio
* Tire Diameter
* 4 spd or Auto (Convertor Stall if known)
* Intake/Carb/Exhaust
and,
REALLY helpful if you know the REAL Engine Compression Ratio ? or better yet the Piston part # especially if it's a BB Engine ?

I guess I did not ask the question correctly. I know the cam that I am going with. I understand how to solve for the correct cam. I know I don't need the specs for my current cam to chose my new cam. I am just asking for the specs of the cam part number that I posted since I can't find it. I want to confirm that what I want to install in the car is not similar to what is in the car currently.

Thanks for the help. I appreciate it.

I think you might have a bad number.   Are there any other numbers?  I think they are on the back of the cam of the cam from some suppliers.

I checked my 2001, 1997, 1985 and 1970 Mopar Performance/Direct Connection/Hustle Stuff catalogs.

Try running that number through a google search.
People are willing to help but it looked like you wanted a suggestion for a better cam. THAT is why you were asked about the rest of the car.
People often come on web forums asking for advice and give such inadequate information, they might as well be speaking Japanese. Most people I know want to be helpful but to do so, the person seeking help needs to be thorough.

I will confirm the number and circle back. Thanks for looking in your books.

I googled the number before I posted here and came up empty. I expect I may have the wrong number will confirm.

I was not clear I agree. It was very early this morning when I posted that and could had been more clear.

Thanks for the response.

If you can't get any info, attach a degree wheel to it, set up a dial gauge and lay it in some v blocks then mic the lobes for the lift.

I didn't think you could determine what the cam was by the numbers on the MP purple cams.

I know none of the ones I've ever seen had a "part number" on them.

I have a 509 cam here from about 20 years ago, it has no numbers stamped into it at all.

I also have a 528 cam from about 4 years ago with 373024 stamped into the back.
The part number for the 528 cam is P4120659, so I don't see how the "373024" corrolates into anything usable for the consumer.

I've always checked them with a degree wheel during installation to verify the right cam came out of the box...... And on a couple occasions, it was the wrong cam in the box.

I never understood why they wouldn't have the part number stamped into them.

Years ago, 6 or 7, I too wanted to confirm the actual numbers on an old purple shaft cam I installed in 1986. Upon taking the motor apart, I too noticed no part number stamped anywhere. However, there was a paint daub on one end. Called Mopar parts, and within a 5 or 10 minute conversation, they were able to confirm what model of cam.

The colour of the paint daub determines the model.

[c00nhunterjoe]

I had a 484 and a 509, both painted pinkish purple with no relevant numbers.... degree wheel is the only way to know.

[PRH]

If you can measure the lobe lift fairly accurately, you could be fairly certain of what you had since all the MP cams have different lifts.

Just multiply the lobe lift by 1.5, and see which MP cam is closest to that.

[Sixt8Chrgr]

Here is a picture of the end of the cam

[J.Bond]

Yup, that is the info you need.....

Phone that info into Mopar, and they should be able to confirm the model

All purple shaft cams are purple, hence the name, the paint daubs on the  end dictate the model.

Actually on another thread here, the term, paint daub crowd, was used to describe some members here.

[J.Bond]

Hey sixt8;

If your on the phone checking out that cam. Ask them if it's possible to get a list that we can post here for future referencing.

[PRH]

The new .528 cam I have here has no paint daubs on it.
It doesn't even have much purple paint on it.
They must be saving on paint....... Only the area between the first 4 lobes is painted.

The old 509 cam I have here only has the orange stripe daub left.
I don't know if there were other marks there before, but all that remains is a raided orange stripe.

I quickly measured a lobe on the 528 cam with a caliper.
1.222 smallest reading, 1.571 largest reading....... .349 lobe lift, which is .5235...... So I guess this is a 528 cam in the box.
