I was trying to figure how to say dual exhaust cars excluding big blocks with W/Z manifolds and didn't do a very good job of it.

This part is installed on pass side exhaust manifold to cap where the cross over pipe would attach on a single exhaust car.

Not sure, but don't the Big block have wider distance between studs?
Alex72, if you have headers, it ain't for you. This is not a blockoff for the intake passageway.

Have to wonder, ask, why could not one modify the crossover pipe to work? Cut it and cap it on the driver side and reroute it on the passenger side to the underside of the chassis?
