1973 351C 4V Exhaust Manifolds


Recommended Posts

Got my exhaust manifolds cleaned up in preparation for installation back on the engine for my Mach 1. 

RH: D0AE-9430-G with casting date of 3F19 (June 19, 1973)

LH: D1ZE-9431-BA with casting date of 3F23 (June 23, 1973)

 

This car was built 7/5/73 so these casting dates line up nicely with the build date of the car.

The RH manifold apparently had a tendency to crack over time so I was happy to see that mine had no evidence of cracking.  These manifolds are in amazingly good shape for being 44+ years old.

Wow. Very nice. The factory 2v cast manifolds also crack on the right side as well. I happen to have a cracked on in my parts bin.
