I know that this is the small block forum but I´ve already started the thread. When the engine is removed I want to change my 2-speed transmission. Is there a "plug and play" transmission out there in 3-speed or better 4-speed. A Transmission I dont have to change anything?

Thanks

 

And now it's no longer the small block forum. The TH350 is as close to a bolt-in replacement for the Jetaway as you will find. The 200-4R requires a little more work. This has been covered many, many times.
