If someone made a Pontiac block that was longer, the length of a BBC and Tiger style heads were made to fit, I would call it a Pontiac race block. Even if it used a BBC crank.
Not into the idea of a BBC style head on it either. We already have that with the Warp and I dont care for them.
I understand it still would not be quite the BBC level, but dont care. Might as well use a BBC at that point.
A big ol Tiger style head would have tons of flow and more room to do things. It would be great beating them with inline heads and watching them scratch their own heads.

Why don't you make this block? I'm certain All Pontiac could put you in touch with the people that could do it. This reminds me of the people wanting a 2000.00 dollar replacment block because the others available are to expensive. Race sruff is expensive. Pontiac race stuff is more expensive. Pontiac had pro stock heads on BBC engines years ago. Was that a Pontiac engine? Based on some people's opinions I would say yes. So get one of those and retro valve covers and front cover. Walla basest pontiac engine around. The next level is different for everyone's programs. If you need a one off block to get there then move that direction. Very few people would purchase these parts. It's not cost effective from a.business stand point.

John Clegg campaigns one of those engines in a firebird that he races 9out of Texas).
Short Stroke deal (like 3.3" stroke range) with a 4.5" bore range piston (not going to give away his actual numbers), Pontiac Part Number BB Chevy Cast Aluminum Heads, etc,etc.

Lots of $$$$$ spent on that deal but was a champion recently in the class he runs, I believe.

Most do not have access to Clegg's money or racing background. They own one of the old HO RACING Trans Am race cars.

So it is possible to run a chevy engine as a Pontiac Part Number engine legally in racing classes but in reality except for the part number it is a custom chevy engine.

If you are talking about that BBC engine with the "Chief' heads with a Pontiac part number on them, I hated that engine. They were better heads than the Chevy BBC heads at the time. I know someone who had a 86 Pro Stock Bird with that engine.
Car is still around here, VERY light.

Let's forget about Pontiacs for a minute and just look at engine design. This can be debated, but hard to argue with years of results. A given bore size can only handle so much valve size. A certain valve size will only flow so much air. Increasing bore size allows you to increase valve size hence airflow. That allows you to increase CSA and make more HP.

Using the Mopar wedge platform for discussion, these engines have tall decks 10.725", bore space is 4.800". The OEM stroke on a 440ci is 3.750". Indy Cylinder head has spent a great deal of time developing bigger cubic inch and cylinder heads to make more power. For just under $40,000, you can purchase a 1350HP, expanded bore space engine with non wedge Predator canted valve design, 655ci that makes less than 2.10 hp to ci. That engine is the highest HP engine Indy sells.

Indy's most popular designs are Hemi / Wedge combinations targeted at the Nostalgia market making less than 1350 HP.

Not quite sure the Pontiac market is ready for $40,000 engines to become the norm used in bracket racing.
