I run a 58MM BBK, but it's really only because it was already on my car when I bought it.
I run a ported manifold with my LE H/C package.

No idle issues

58mm Summit, looks like a really nice piece sees to work well. although my IAC counts are high not sure if it is because of a vacuum leak or something?

I am running a stock t/b bored to 52mm with a matching airfoil. Got that done and it powdercoated black to match the slp intake for less than an aftermarket 52mm.

I had a 52mm Holley and now have a 58mm Holley. No problems with either one, they both work great with nice gains.

I'm running the Holley 58mm throttle body with no problems but I would rather have the Arizona Speed & Marine 58 it flows the most out of all brands.

Summit Racing 58mm here. Love the performance. Idles smooth as hell. Looks real good being polished and all. I would highly recommend it to anyone. Heard alot of bad about the BBK units.

I will look into summit just to see what they have. I did not even know they sold their own brand of LT1 throttle bodys. I just like the look of Holley.

As far as I know stockers can only be bored to 52mm...

I run an ASM 58mm with a ported intake, h/c etc... It's fantastic, feels amazingly better than the stocker. I would easily recommend the ASM as the top quality throttle body for our cars.

Edit: I heard of too many sticking issues with BBK and Holley, you get what you pay for...

Looking back, I would have bought an AS&M over my BBK. Granted I haven't had any issues with the BBK, but I agree the AS&M is nice. If the Summit had been available at the time, I'd have bought it.
