318 MAX fuel economy builds?

That is the thought process. But this build is on hold until the car is up and running again. I have to do an exhaust.

Rhoades does have MoPar roller lifters. Click below and scroll down to the second to last on the left for V8 applications, all the way down on the right is a listing for the 239-6 cylinder as well. The listing stops at the year 2000.

Maybe I’ll find a roller cam that meets my spec? IDK?

I would be all over those roller lifters for that 5.9. I had no idea they had them for Mopar and I just bought a new set of vmax last summer. I can see that you def have an advantage on me in the friction area. I just gave away a good 5.9 mag engine to a buddy. lol You are using the magnum heads I take it?
