It is possible to fabricate any engine to bolt up to the Opel 4 speed All it takes is time and money. The Opel transmissions are pretty weak, so you would be best served to change the transmission if you plan to upsize the engine. Saginaw transmissions are plentiful and I am sure somebody in the forum has a transmission mount for one. I might even have one.
I keep my two 72 Vega's original with the 140 and Opel 4 speed, so don't junk the engine or transmission. I like to keep spares.
