Hope that helped.
LOL, I just realized that about the transmission, I was too busy looking at the code for the gear ratio that I didnt notice the tranny part! I have more pics of the motor, and I believe that it is indeed a crate goodwrench, I need to find out more about it though, because the stock was a 5.0 liter, and those were usually 305's right?
