Throttle bodys........ What are you using? I just had a little advice from one of my freindy LT1 members here on LS1 tech on not to use the Holley 58mm Throttle body. Why? i dont know. I have already have the trottle body but mayby if it is no the one needed for my setup, only then will I return it from where I bought it. What is the best throttle body for the LT1 and what do you fellow LT1 fanatics run on your ride.
Thank you,

Im running a 58mm BBK, but the idle quality is crap. - when bbk made the TB's they drilled the IAC passage wrong and so the IAC always changes the idle speed no matter what you set it in the computer..- usually a 3-400rpm variance.
AS&M's is much better and so is TPIS's but TPIS only makes a 52mm but people say you dont notice between it and the 58.

I have a ported 93 LT1 intake...

NO idle issues in my 1995(Vette) with a 58mm BBK, however, a buddy returned his BBK and went back to stock becuase of idle issues( 93 vette).
