That was my line of thought too… But I’d make an argument from a reliability perspective that Gen 1’s V8 engine is more desirable than Gen 2 and 3’s V6 HOEB engine. That leaves me more unsure.
The 6.2 was relatively low tech, a good medium displacement v8 for its day, but wasn’t really built like the current 7.3 or the 3.5TT. It will be a wash, honestly. 6.2 parts are getting harder to source, so someone needs to come up with a low cost 7.3 swap kit. The 3.5s though, there’s quite a few of those out there so parts availability -I think- will sustain the Jens that use the eco. The hair driers have proven pretty reliable so far.
@Old-Raptor-guy has a thread about long running ecos’ and some of them are pretty impressive.
I’d buy a Jen Juan if it was inexpensive enough and didn’t need a cr@p ton of work, but I’d probably be more likely to squirrel away some pennies for a newer Rap - Jen Tres maybe.
It’s not like I’m doing the wrenching on the motor or the rest of the drive train. I’m good for some bolt ons, and that’s where I draw the line for the sake of all humanity.
Any Raptor of any Jen will hold probably 10-12k more than a peasant F150 of most vintages.
