Default Throttle body ?

can anyone tell me what make and size throttle body Callaway uses on the 757 package on Zo6 ?

have an opportunity to purchase a used one. want to make sure it will work no the LT1. have done some research, to no avail so far. my next move i think is to call Callaway.

I feel like calling Callaway is a very easy, quick and surefire way to get your answer. Why don't you just do that?

That looks like the Katech throttle body with machined flattened cross bar.

I got one of the first 757s, when dynoed, it was down about 100HP. After consultation with a Callaway engineer, it was decided to change a couple of things...among them the upper pulley and throttle body, intake runners and various other tweaks. Parts where sent to me and I did the install and dyno testing to verify that all 757 ponies where present...and they where

I have wrenched on and seen other Callaway 757s that are not EXACTLY like mine, but my car headed there before the 1st 757 left. They also knew in advance that I would be taking it apart to mod extensively as soon as I took delivery. Initial dyno testing results delayed my build.

Does further modifying a Callaway car void the warranty you get through Callaway? Logically, I would think it does, therefore defeating the main reason for buying a Callaway in the first place, but I am not sure.

Warranty was of no concern to me, once I put 2k or so on it. Then itís mod time...
