I had both trannys in my car.. I have an 83sc. I have alot of power. When I was at 325-350hp I used the 915. I never did any hard lanches and it was fine. 1st gear was usless.
Know I have a a 930 4 speed tranny in there. I do have alittle shorter gears though.
1st goes to 60 2nd to 90 3rd to 130 and 4 i could not tell you did not go there.
you are going to have to go with a early year 4 speed turbo tranny. They were shorter. The original 930s where the same chasis as the sc the later 930s were longer and will not fit in your car. Unless you do modifications. You will need a 4 speed tranny from a 76-77 yr 930.
I love my 4 speed by the way,I had it rebuilt and works flawlesss.
