i have a 2001 dak w / V6 3.9 stock. i might be putting a new engine in soon. would 1.7 rockers with stock cam or a RV fit and work. BUT iam not putting it in. my repair shop is. i dont want to have to do to much spacial done to get to work. it has a 4.10 gear that goes into O.D. at 30 MPH. i drive in town only. max cruse speed 50 MPH most if the time.

 

I would not think it would be worth the money. Not really going to see any gains as far as the application....
Just my 2 cents

 

Save your money, or change the cam.
