I would say the next thing should be an intake and then maybe a cam. I like the holley systemax intake or the Edelbrock performer...then maybe an e303 cam.
Yeah if you actually do have that 87-93 motor...If you find out its an 86 then you need new heads and pistons to have a good combo. Heads can come after an intake and maybe before a cam.
you can get a mass air adapter off ebay for 40 dollars. I just got one. then all you need is the MAF meter.
