Reliability of dodge 273 and 318 V8?

Looking for a new older american truck. Best friends a chevy guy know plenty of those, wife likes ford know those ok, dont know anything about dodge engines. Looking at older trucks founds several GM and couple fords, and a couple dodge, 70's and 80's trucks, have the 273 and 318, are those any good? What are common problems with them? Lng term reliability? Ease of repair and maintenance? been a toyota guy since forever, own a 86 4runner but need something fullsize to use as mostly as a hunting rig and another off road toy. wont get a newer truck, dont like having fancy computers rather have a good ole american pickup. Dont wanna hear bashing of the other trucks, just reviews of old dodge trucks.
i know decent amount about mechanics and maintenance and repair of vehicles, do most of my own work when im not feeling lazy

Theyre pretty good for car bombs

stay away from the 273, the 318 on the other hand is a great motor all parts are interchangeable with any other smallblock chryslers.

I had 2 318s, Both gave me no trouble. One needed a new starter at about 84,000 miles.
