Larry,

My '87 is up on blocks right now. It is getting an Edelbrock Intake and a Carter AFB. I am doing away with the leanburn and mounting a Mallory Hyfire 6AL where the factory computer lived. All I need is an early Electronic distributor with a vacuum advance pot. The PO eliminated half the emissions equipment and made it run worse. When I am done with it, it won't have to pass emissions (27 years old), but I guarantee it will run cleaner than stock, without a cat. And with one large exhaust pipe, like my Cummins.
