Is it still possible to get performance camshafts for the 3.9 engine?

 

Yes. Check here...

There may be other places that have some as well, but thats the only one I know of off the top of my head.

 

Thanks! Does the LA and Magnum engines share the same camshafts?

 

No they are different.

 

Uh-oh, I think they only offer camshafts for the Magnum...

 

I have a "purple" cam for the older v6, with lifters, new in the box....MP part number is p4452810....

 

If it is your intent to improve your current engine, you will need a better intake manifold. I advise getting an 88-90 TBI intake and having the top machined to take a larger 2 barrel carb, like what was found on the 360 and 400 engines..
The 87 BBD carb bolt pattern is too close to the Holley to allow just buying an adapter.

I put the bigger 2bbl carb and a 360 intake manifold on a 318 once, dropping 2 sizes for the jets, and it ran very smooth. I only lost 1 mpg in mileage...

With a purple cam, you will need an improved intake and exhaust system to get the best performance gain.

 

I think my Dakota really is a '88, as it has the TBI. I've been in contact with thefastman.com, and will probably buy one of his TB's. I will also get the Edelbrock headers from Hughes Engines.

Thanks. Do you know the specs on the stock camshaft as well?
