This may sound like a total noob question, but I'm having my G54B rebuilt for my 1984 Ram 50 sport 4x4, and I need to take the engine out first.. Wondering if I can drop it through the bottom? Or does it need to be lifted out with a cherry picker? I know some trucks you can just drop the engine down and don't need the crane, so... Also, I'd really appreciate any one who has some good advice/experience taking these engines out. It's my first time!
