Niether. If you have a 1993 w/350, the engine's a TBI L05. There's a good chance that it's a 9C1 with that 350, although in that model year some were offered to the public with that engine, I've come to understand.

If it really is a 350, the SPID label in the trunk will have L05 and the VIN code for the engine will be 7. If it's a 305, it will be L03 and E, respectively.

Its a 350... Its my buddies car and he was wanting a cold air intake and he told me that the air filter was ontop of the engine, so thought is had a carb. I havent looked at the engine myself but i thought it had an lt1

It wouldn't have had an LT1 or L99 until 1994. IIRC, 1988 was the last year for domestics to have a carb.

FWIW, a CAI isn't going to help much on an L05. The big restriction on those is the stock "swirlie" heads and restrictive exhaust. The next worst problem is the cam profile. Once you have solved those, the TBI220 is next, along with a better intake tract and reprogramming.

Actually, reprogramming would help right away, since you can enable Highway Fuel and Spark Modes and trim up the timing tables a little better. If memory serves me, the TCC lockup points in that late TBI factory programming were pretty weak, too.
