One of the best 318 I ever had came out of a 69 dodge truck, fun engine, weird single plane 2 bbl carb, and front sump oil pan.
I beat on that old truck hard, it was rusty.
The day I bought it, drove it down the interstate 60 miles home in the rain.
I ended up soaking wet from the waist down, floor boards rotted, but what do you want for $50?
Fixed the floor, and drove it for a couple of years, it finally got so bad sometimes you had to slide the cab over to get the clutch to work.
Rear end finally went out, pulled the engine and junked the truck.
Slid that engine in a duster. it was a really fun car to drive.
Ended up selling the engine to a guy saying it was a match to the one in his boat.
