There is another number preceded and followed by a screw looking stamp. That number is 3C3. An 80 appears beneath the exhaust manifold. All the numbers are visible with the starter removed. The harmonic balancer is 28oz external imbalance with 3 bolt holes. 6 bolts per valve cover. Any idea what it is?

Didn't you just answer your own question? It's a Windsor.

It's 8 bolt valve cover (351M/400) and when I mark the stroke it comes out to 4 inches (400).

4th digit of the VIN is the engine code: H = 351M; S = 400.

400 B&S: 4.00" x 4.00."

351M B&S: 4.00" x 3.50."
