I think your onto something with the roller cam bearings giving the mains more oil. I think it was LPI that drilled out the main saddle oil feed hole and the lifter galley’s to make both bigger to increase oil volume. That might be worth a phone call to Mark Luhn.
Also in a extreme case I think Mike and Eric went above and beyond to feed the #2 main extra oil on their fire breathing nitro motor. There is a thread on here about that somewhere about how they got the bottom end to live.

Roller cam bearings are also going to give you 5-10 HP just from all that oil not dumping on the crank. Power to be had there per the folks in the know.
I drill everyone of my main bearings the same size as the oil hole in the block on the singles and on the tri holes the one on the "tab" side of the 3 holes that intersect. It gets the shot of oil.
Heck with that "slot" those bearing as is. Oil still hits the back of those bearings.
As straight a shot as I can get.
BTW, why can,t we get priority main oiling in our aftermarket blocks ? Why cant it get re routed. Is it possible ?

I'd be very curious if the person that told you this actually tested this or just guessing based on theory.

Someone who has made big NA power with a Pontiac. As good as they get, who am I to disagree? I passes it on, do what you like with it.

Nothing to do with it, i've ran both.

Did you dyno the engine with a slipper cam then dyno the engine with the exact same(why would you) grind cam but 50mm and needle bearings instead of babbit ?
That being the only change ?

My neighbors Grandfathers best friends Uncle who lived across the street from Grumpy the Cat (RIP) tested this very same deal and found six horsepower. However they don't know how much of the power was from the two different cam cores, reduced friction or controlled windage. He felt like he completely waisted a lot of time, money and effort on the project...FWIW

BTW....he was not related the the guy that lived across the street from Tom Molnar. But did give Tom's three legged dog biscuits occasionally.

It appears you want some of me.........OK, got your wish.

And once again Thanks again Aaron and Billy for sharing information on your build.
I hope that motor exceeds your expectations on longevity!!

I have no idea why you are bothered by this post. It's actually very informative if you understand the basic theory of making horsepower. You need to stop smoking that California funny stuff... it will make you less paranoid (seriously it's a proven fact that stuff makes you paranoid). Not everything is about "Dargncar". In fact very little is about you!

You know the old saying about teachers ? Those who can, do. Those than can not ,teach.

Well Xerox, those that can, do. Those that can not reverse engineer.

So, here is to you Paul. RevEngTTFMF!!!!
You need a new acronym so I thought I would offer you one. You know, if the shoe fits and all .
