I have a 1985 Rocky EL, with a Toyota 3y Gasoline engine. Is Carburated with regula point and condenser Distributor.

I heard that you can interchange the parts from a Toyota 4Y Gasoline engine. That engine is in some Toyota Hilux (pick Ups). They have a Electroncic distributor. Ia m thinking a swaping that for my mechanical one.

On the carburated, I have heard that swapping a caburator from a Toyota 4k engine helps on the gas mileage.

Any thougths, Comments, or opinions?

Thanks
