Unless you've got a stroker I don't think a 58mm would really help you out at all. With heads and a cam you would probably want to go to a 52mm but the 58mm is for the bigger cube motors or high revving 350's.

A 58mm is unnecessary on all but the most heavily modded motors.
The stock 48 can flow more air than the engine can use.

I put a 58tb on my stock L98 Iroc just for ***** and giggles and haven't had any probs it does make the intake sound more noticable. I had one laying around so I used it. but don't go out and buy one thinking it's going to be a big performance gain Get some headers
