87 squarebody question
I'm more familiar with 67-72s and came across an 87 for sale. It says it has a 305 and 3spd auto. tranny. I thought that it should have a 4 spd auto. I am I mistaken? I know someone could have changed it but what did they originally come with? Thanks in advance.

Re: 87 squarebody question
I'm guessing the overdrive trans is optional. I have one with a t350 and one with a 700r

Re: 87 squarebody question
Some 87's has the 3spd Turbo 375. Its a light duty Turbo 400 with a Turbo 350 output shaft. Don't know why GM did this.
