For me these are from experience/working on/owning em.
1. 300 i6 ford
2. pretty much any d-series motor from honda
3. old 2.5 iron duke


any others im missing?

Easily 3800 series 2 . This engine is a freaking tank.
Then I would probably say an old Chevy 350
Not sure about the last one

i think the iron duke 2.5 4 cyl is in the same family as the 3800. the iron duke is also known as a 2500.

It would be hard to list 3 but my top 5 have already been mentioned.

if by DD engine you mean the maintenance schedule is followed correctly I would venture to say a 12 valve p-pump cummins would outlast nearly everything.

A gen 1 SBC, 3800 series II, 300 I6, and 4.0 jeep I6 are all tied for my "don't do anything but add oil when necessary and still crack 300k mi" award.

chevy 350

ford 300

for 351



all of them can/will go forever

If I had to go with one brand for most reliable.

I think it's hand down Toyota.

Volvo close second.
