318 MAX fuel economy builds?

DMO,
Post #140. I have had NO issues with Rhoads lifters, have use a couple of sets over the years. I make my own now using stock lifters.
Also agree with others that they are a waste with very short duration cams & may well be costing mileage & performance. Short duration FT cams will have low valve lift [ compared to longer duration cams ] & will have even less lift at low rpms with Rhoads. The loss of lift might degrade performance.
Post #139 lists the variables with Rhoads which you may not feel, but is there.
