Nothing special about my Greenie here, it has a Briggs in it with a hole in the side, but it is complete so just needs another motor in it, and even though I have a V8 sitting in the garage, I'm not sure that is an option at the moment.
The 302 V8 in my 92 Fairlane will probably outlast the body. I might work on sticking on a VC auto drive if the gearbox can take the torque.
I somehow saw the writing on the wall with Greenfield. Weird this anachonism was producing push mowers while know one knew about them!
