Back in the 80's I had a 50 Ford pickup. It had a flat head in it and when winter time came, I had not checked the anti freeze in it. Well after a hard freeze one night, it developed a crack in the block. Parked it for a while after that.
I liked the truck a lot but couldn't afford a new motor.
A neighbor across the street worked at the local Chevy dealership and he had a garage behind his house that he worked on his drag car and other things.
He told me one day that he had just taken a 262 and transmission out of a car that the owner wanted a bigger motor in his. He offered to put it in my truck. He said they only made this motor a couple of years and didn't know how much trouble it would be but I told him to help me push the truck over and he could do it.
I didn't check with him for a good week and low and behold, he drove it back in my driveway.
It was an automatic trans. and from what he told me, it bolted straight up including the driveshaft. He said all he had to do was make a small adapter for the transmission to the frame and everything went right together.
I couldn't believe it.
From what he kept telling me, the truck was made for a Chevy motor more than the Ford flathead.
I had to make a gear shift extender for the floor board shift and this thing sure put some rubber down on the road.
The rearend was a good match and it didn't over rev. or bog down when driving. I finally traded it to a friend for a Corvair Monza.
Wish I still had both of these autos.
