    I'm a huge fan of Chevy small blocks. Had many over the years. Awesome power, decent fuel economy, easily maintained and repaired. Very dependable motor. If you can drop it in a jeep. I just became your biggest fan. :)

    The 350 isn't any bigger externally than the 305 providing that is a Chevy 305 you are replacing. Everything should bolt right up as they have the same bolt patterns. It is always fun to go bigger. Both motors work great in a jeep. You have the quadratrac which if I'm not mistaken comes with the GM TH400 tranny. What an awesome setup. My only question is did Jeep use an adapter plate to get the tranny to mount to their motor, or is it custom drilled to mount to their motor making you have to drill you own mounting holes on the bell housing to make it fit the 350?
