Nice power level. Not record setting but 1050 is a lot of HP.

Criteria for this build was Bracket racing,We sizes the induction tract to make peak HP at 7200RPMs keeping the usable power curve at or under 8000RPMs. Bill C.

Cool!

Nice!

Very Nice build

So what part/piece of the engine is actually factory Pontiac?

Timing cover, distributor hold down, bore spacing, valve cover gaskets.

What does that matter? It's a race engine...

I’m thinking that no matter what brand of engine you chose to run, when you get over 1000 HP, you’re pretty much all aftermarket parts.
This is the race section right?

So why not just go with a big inch Hemi and make custom billet aluminum valve covers with the name PONTIAC on them? Kinda like when Pontiac no longer made its own engines and used big block Chevies with Pro Stock "Pontiac" 427 heads. Remember those? That wasn't a Pontiac engine either, but some will say it was because the valve covers had "Pontiac" cast on them - same as my Hemi idea, and probably a much stronger running engine seeing it's a race engine.

Well then for that matter, why bother making ANYTHING aftermarket for Pontiac at all? It's that sort of thinking that prevents anything from evolving.. I guess next you'll say we should all be using iron heads and 041 cams.... nothing like going backwards, huh. Some of us don't live in that box labeled "50 year old technology", nor do we think that way either.
No offense, but your analogies are way off base and don't apply to the topic.

No offense taken at all. It is my opinion that there becomes a point, where I can't see the claim that the car, or engine, has enough original components to be called "Pontiac."

The Pontiac engine certainly has its limits and can only be competitive to a point - this was learned back in the late 1960's/early 1970's when some Pontiac racers were installing Hemi engines in an effort to be competitive AND keep up with the Hemi dominated field.

When you take something like an engine and completely redesign the block from top to bottom and simply retain those identifying features common to a factory Pontiac engine such as head bolt, oil pan, and timing cover placement, and then add a never available factory top end - well, the engine has steered so far from a factory piece that it is really not a Pontiac engine anymore than the drag racers who inserted Hemi engines in their Pontiac funny cars.

So why not simply follow the earlier racers who were unable to compete using a true Pontiac engine and went Hemi? Just carve out some Pontiac specific valve covers as the Pro Stock guys did in early 2000 and slapped them on 427 Chevy big block engines and convinced themselves and the racing community that they weren't Chevy engines, they were Pontiac engines because the name on the valve cover said so. Pontiac logo valve covers on an 811 cubic inch Hemi would be a better competitor, maybe even cheaper to build, and I am sure the racing community could be convinced that no, it's not a Chrysler Hemi, but a Pontiac Hemi because the valve covers say so. With the broad acceptance of the LS engine in a Pontiac as if it was made that way, I think the Pontiac Hemi should be a consideration.......and a track competitor/winner among the real racers who actually win. Might give them a run for their money.

nice piece for sure. interesting comments about wet decking hiding in there

I wonder what it is going into?

117 is correct.We have other Pontiac cams done at 118-120 per application.Just for info current NHRA Pro-Stocks at 119.5-120LSA.Bill C.

Wow! Now that's interesting! Didn't know that Pro Stocks were that high, LSA wise.
The engine you built for this customer is similar to the one I have compression and horsepower wise. In my case we went with a 114 LSA, I may try something a little wider the next time around.
