You don't have to convert to mass air now. Others may disagree, but IMO as long as you aren't changing out to a radical cam or adding a blower, you can still keep the SD and swap out the heads, intake, TB. Many people have run SD cars well into the low 12's. Don't know if they still do, but back in the day they even used to make SD specific cams. The mass air won't actually make you more power than the SD, it will however allow for more adjustability and choices down the road. I didn't swap to mass air on my 87 until I put a vortech on. It had E brock heads and intake,crane 2010 cam, TB, headers, 24lbers, CAI and ran fine.
