Message: What are the sizes for the stock 3.9 and 5.2 throttle bodies, I'm trying to figure out which one I have. The truck has a 5.2, but it used to have a 3.9. I'm not sure if the new motor came with a new throttle body or not. I know on the list of things I bought all that showed up was the motor and a new HD radiator. I got this list along with invoice I got from the mechanic that put it in.
