Just wondering if the camshafts, pushrods, and lifters between the LA 3.9 V6 (Pre-Magnum) and 3.9L Magnum can be swapped? Just brainstorming at the moment and thought of at some point replacing TBI camshaft setup with the Magnum one.

is the LA 3.9 a roller cam block? if so, I see no issue on swapping them. I don't know anyone that's done it, but I would imagine it's a bolt on swap.

...are the specs different enough on the Magnum to justify though? I know several Dakota guys who have had cams re-ground by delta cams for just over $100. They have several thousand miles on their reground cams and no issues.

might be a cheap way to get some more oomph for the tiny V6.

Or Bullet cams for $125. Bullet has a huge list of hydraulic roller grinds, including several 209 degrees @50 and smaller.

some years of LA had an extension on the cam to drive a mechanical fuel pump

Magnum 3.9 V6 cam timing
(250 degrees advertised intake duration with 31 degrees overlap)

the airflow capability of the Magnum intake port is significantly higher, around 30 cfm

Thank you. Yes, it is a roller cam engine and has an electric fuel pump. I believe all 3.9s are roller cam but, the 87 still had a carburetor so it used a mechanical fuel pump. Anyways, I figure I would ask because at some point I will do a timing chain and tensioner so I have thought about the V6 Magnum camshaft since I can get one cheap but, we'll see.
