I have a 72 half cab that was my daily driver in high school back in the 90's. I am wanting to get it out of the barn and start driving it again. It has a 200 that was pretty worn out back then. I have a 250 with a c4 complete out of a 76 Maverick. I am curious here who all has done the swap from the 170/200 to the 250 and if you think it was worth doing?
