74 BB Exhaust Manifold Date Question

[Victor S.]

Hi All -

Would it be possible to have an exhaust manifold date 12 days after the engine assembly date and it be original to the car? Not sure if all the factory engine components were on the car at engine assembly date or some were installed later??

Thanks,
Vic

Victor,

If you have a 1974 Assembly Information Manual (A.I.M.) check to see if exhaust manifolds have separate part number and bolt torque specification. If so, then manifolds were affixed at plant. If not, then manifolds arrived at StLouis attached to engine. Attached at plant would cut you some slack. In any case, are they prior to car manufacturer date?

Thanks Dave - I cannot find exhaust manifold part numbers in the 74 manual so they must hace arrived at St. Louis previously attached

All Corvette exhaust manifolds, small block and big block, were installed at the engine plants.
