Well, if you look at how the oil the lifters you can see it’s a design issue.
There are compromises in EVERY production engine out there.
Chrysler spent all their money on the G3 Hemi, which NA is less than impressive. I get that they were looking down the road to supercharging but that doesn’t change all the issues an NA Hemi has.
IMO, the Hemi was brought back for the marketing side of it. I’d rather they would have spent the money developing a better wedge head engine than the Hemi.
