i see posts and info about 3.7, 4.7, 5.2 and 5.9 cnc ported heads, but i have never seen anything about 3.9's. did our motor just get completely forgotten about???

probably, not much aftermarket for our 3.9's

ur a machinist, you should have some connections!

Your a machinest? Do what Dwight did, figure you what works, and sell it on the site. If we can get enough 3.9 parts together to make it worth it, I might keep mine instead of swapping in a 360

Sell ported 5.9 heads that come free with a v8 swap wiring service. :jester:

soo a 3.9L port/polish should be 25% cheaper than a v8 cnc port/polish right?? It should be almost the exact same as the 5.2 minus a cylinder but i've never seen the 5.2 magnum heads up close personally

Being a machinist, doesn't make you familiar on setup and programming of a cnc. I'm an auto machinist/builder and just finished my first semester of CNC training. Still have a good deal to learn.

i am a cnc machinist/programmer, but the setup and programming is totally different. auto machinists have special fixtures and equipment just to hold heads.

plus the machine that i run is a little too big to machine heads....

but i do have access to my old shop that i used to work in. here are some pics of me machining out the center divider, cutting the runners down and boring the tb bores to 50mm. it is still not finished yet. i used to take stock tbs and actually cnc machine them into 48mm instead of just using a dremel to grind out the step and air horns producing only a 43mm tb.

here are some pics:
