I'm not a Toro expert, but in the quest to find a better SBO exhaust manifold, it appears that the Toros did not use the under-the-oil pan crossover pipe. Is this true? Does anyone have a picture of a pass side manifold from a 77-83 small block Toro? Thanks.

 

Early BB Toro's had no crossover. The passenger side would probably fit the chassis because it is very similar to all V-8 manifolds used for the right side. The left manifold most likely wont work as it is shaped for the Toro and curves out and sorta upward. 1979 and up Toro's used the 350/307. I believe they had a flattened manifold that was sort of header like but am not sure if they flow any good. I believe my 83 Riviera 307 has this type manifold but cant get pictures because the car is in storage not near my house.

 

Right. I was thinking normal SBO LH manifold and Toro RH manifold. Note the Toro used a small block from 77 until the transverse drivetrain came out, since the last BBO was made in 1976.

 

mine is out at the powdecoater. maybe when it gets back
I can snap a pic if you still really need
