The repro, correct manifold often turns up on Ebay but can be bought from Thornton Reproductions....they specialize in 442 stuff but do have the S manifold. Im not convinced the oil pan is from a Toro....the car could have came with a 2 or 4bbl carb both of them single exhausted. The only way the car came with fact duals is if it had the Starfire engine. If it did most likely you would have the correct manifolds. The manifolds on your car are not Toro but single exhaust manifold(s). The passenger side manifold is the same for single or dual exhausted cars....the center hole on the passenger manifold is capped from the factory for duals with a bolt on cap. If nothing can be solved at 442.com with block numbers I would assume the engine is not Toro and the original one that your car was built with. A Toro oil pan gives and extra quart of oil....a lot of people in the 70's would swap pans for the added protection of another quart of oil. The sure way of telling if it is a Toro block is to pull the intake and measure a lifter......all Toro 425's had a
921 diameter lifter while the standard 425's had a smaller .842 lifter.
