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. THIS IS THE POINT along with bolt on items like pan, timing covers, heads. !!!!!
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"

Tom. We have the M/T Hemi heads that
BOLTS to a Pontiac block. We have the RA V stuff with different valve configuration that
BOLTS to a Pontiac block. We have the canted valve CV-1 head that
BOLTS to a Pontiac block.
If ya change the parameters away from the std Pontiac block design from the original concept it is no longer a Pontiac because they are no longer in existence as a Make of Automobile.
Increasing the bore spacing and using nothing else related to a Pontiac is already available in the aftermarket. Been done.
Where would the Pontiac aspect come into play?
So according to your ideals, if I run a Small Block Chevy with the Factory designed Pontiac aluminum heads Casting #987, it is a Pontiac and can be run at Pontiac events?
