POLL: OEM exhaust manifolds on your 71-72 402 BBC
Attempting to discover common ground....Possibly establish the part numbers (maybe date codes too) for the original exhaust manifolds.
Note, it's not necessarily what's shown in the 1979 parts catalog, because they may just be replacement parts. Also, 3989343/3989310 is all over the web, but I believe these are for passenger vehicles, and they still might not be the original parts. Also, the same part number can show for those with or without emission ports. I'll start: 1971 C10: LH 3994045 - No Emission ports RH 353030 - No Emission ports Don't know the date codes. Incidentals: I believe the LH was replaced when the engine was rebuilt in 1993. I seem to remember the original busting when I removed it. Can't say the new one is the same as the old.
