Hello! Part of the advantage of having a junk removal business is that you get interesting things. A few weeks ago, two automatics came in on a load. I know a lot of guys here like automatics, and have a lot of experience with them, so I'm hoping that someone can help me ID these two so that I can put them in the classifieds. Let me know. Thanks... Chris
Looks a lot like a 350 in first picture. Second has a lock up converter switch. Measure the length and look up 350 by length.
