Passenger side, front, lower on the motor.
either a 285 or a 350... the odds are that its not a turbo 400
How do you change the heater core on a 1978 Chevy Nova Custom with a 305 v8 engine and where is it located on the car? thanks jj

That would be a 2 bolt
It should be in the back of the engine, just to the drivers side of the distributor.
Yes but you might have to change the driveshaft

If the Buick 305 is really a Chevy 305, then the motor mounts will interchange with a Chevy 350.
