The timing cover and valley pan set up?

You are chitting me right? (You guys are calling it a Pontiac Engine based on a Bore Spacing number, nothing else)

1) Pontiac never had "Canted Valves" in production but a CV-1 Head is allowed.

2) Pontiac never offered a 4.5" stroke from the factory and yet 4.5" and a 4.25" cranks are "allowed" as being "factory".

3) Pontiac Engines did not have "Shaft Rockers" on their V-8 Engines but shaft rocker systems are allowed.

4) Pontiac did not have 6.8" long, 2.20" bearing diameter Rods. They are allowed.

5) Pontiac did have a belt drive camshaft system for the 6 cylinder engine so I guess we could allow the BOP belt drive stuff.

6) Pontiac never had a 4.375" Bore Block but that is allowed.

So the only thing that makes the "Pontiac Engine" a "Pontiac Engine" is a engine with a 4.62" Bore Spacing.

So I can go to my Ford SOHC Engine buddies and buy a raw block designed for a 4.630" bore spacing vs a 4.620" bore spacing, have it machined to a 4.62" bore spacing and take it to all of the Pontiac Events and call it a true "Pontiac" engine (as you guys are saying THAT is what makes a True "Pontiac" engine. A engine with a 4.62" bore spacing.

You guys are so out in left field with your "has to be a 4.62" bore spacing" bs it is actually humorous.

It has nothing to do with engineering, It has to do with a single number in a book that you guys are now calling the "Holy Bore Spacing Number". You guys should join the "Flat Earth Society"
