Throttle bodies
I have done some searches and found some info but want some clarification. From what i read the stock LT1 has 52mm Throttle body. I have CAI, Headers, lt4 cam, and cat. Can I tell the size of the throttle body without taking it off? The guy i bought the car from had a bunch of mods done but not sure if he had a new throttle body or had it ported for a bigger one. just looking for some help to determine what I have and what would help performance. Can i put a bigger throttle body on knowing that I am going to get it ported to a matching size at some point? Thanks for any help you can give.
