I was thinking about this the other day. Did GM ever make a gear reduction mini starter for a 153 tooth flywheel SBC, like in a late model application? I know the later 5.0 Mustangs came with one, but have never heard of one from GM. I am interested in it primarily because of weight, so I don't want to buy an aftermarket one because they cost too much for the 10lbs they take off a car that already starts fine. If there is a junkyard solution though, I am all over it!
