3884463 intake dated 8/26/63 for a 409 400 HP engine.
Plenum divider has been milled out, but doesn't appear to have ever been ported. It does have some external corrosion on the drivers side at the crossover passage. Thermostat area is solid. No heat shield, 2 of the old shield rivets need to be drilled out if you want to re-install a shield.
How about $250.00 and I'll cover the ride (48 states only) for
paid sYc members. Non-paid members pay $25.00 flat shipping (48 states only).
Here's a few pics.
