Found this the other night been meaning to pass it along, very interesting read! I believe its originally from Hot Rod Magazine in April 1969 (not 100% sure, but I think that's where it came from). There is definitely a reprint in "The Complete Ford Book", I found a copy on Amazon for like $6 bucks. Hope you enjoy as much as I did!
Great article!!!...thanks for posting seems that may have been done to the 69.5 I6 that I have here in the shop.
My dad gave me that article when I got my Maverick in the 80s. I wanted one of those spoilers so bad.
I have a feeling that 68 Mustang PS gears are the same ratio as ours ... I will have to see if mine goes 3.5 turns lock-to-lock. If less, maybe we have something here. My car is up on wheel skates right now ... might take some effort.
