What's funny is the new MSD distributors come with a warning tag attached to them that says to block the oil filter bypass. I've been doing it for for over 20 years on engines I feel the customer will change the oil and filter on regularly. I have never had a bearing issue or any other issue from doing so. I do see a lot of scratched up bearings in engines running the bypass though.

The point of my post was missed. I'm not surprised that would turn into a "to do or not to do" LOL
The point was that we can't blame a filter for catching everything if the bypass is open. There is oil that isn't being filtered AT ALL. Plain and simple. Doesn't matter how good the filter is with an open bypass. |

Update
My motor is back home and hopefully we'll get to install it soon. Here are the dyno sheets from the first time it was dyno'd and the most recent dyno numbers. This car should be a handful! Sorry about the pictures not being in the correct order. I wasn't too sure how to do that. The 1st two pictures are the most recent dyno numbers!

This new engine is filled halfway up the pump holes so it will need synthetic. I plan on running Amsoil 20-50 in it. Right now I am thinking about plugging my by pass and going with that 150$ K&P screen type that is cleanable. The flow rate is huge and they make them with or without a bypass built it. I would think that if you plugged your by pass and ran the K&P with its own by pass it should not make it to that mode very often. Thats the plan right now. |

The valley pan leak is fixed! Apparently the gasket slipped out of place when the valley pan was being installed! Paul says the oil filter was free of debris and looked good. Hopefully the motor will be on it's way home next week! Standby for burnout video(s)!

Good For Him!!!

I'd be willing to bet Koerner Racing Engines is doing this on every engine they build now. Hard lesson to learn over a $10 oil filter. Especially when ten bucks could be added to the cost of a build. And for what it cost to build these....Customers wouldn't give a second thought to ten extra dollars. Good for Joe Good for Paul And good for Koerner Racing for doing what's right. Clay Clay |

My understanding is that Jeff and Paul were still working on your carb at that time. I may have misunderstood him but when I look at those sheets it confirms that. 1st test was an 850 brawler deal that I think was your carb. 2nd test says it's the Jeffy carb which is one of Jeff's special carbs that he builds specifically for a particular combo.

Full flow oil filters speced for a Pontiac Stratostreak V8 do not have internal by pass valves. The one in the oil filter elbow is the only safeguard in the oil system. Blocking that safeguard allows no bypass whatsoever. If the filter cannot handle full flow at high RPM is will do one of three things, leak externally at the sealing O ring, blow the canister out rupturing it, or collapse the filter media internally, possibly ripping holes in it. Unless you cut open each filter you'll never know if it collapsed the media rupturing it, rendering the filter in by pass mode 100% of the time. If the system overpressures the oil filter it will find the weakest link.
Smokey Yunick calculated that a SBC would need 4, 12 inch long full flow filters at full RPM to filter all the oil pumped through the engine. Anyone here with a blocked by pass have anywhere near that filter capacity? There are much safer ways to filter the oil to a higher standard than any full flow filter or combination of multiple full flow filters do, usually on PY this all falls on deaf ears, as I expect it will currently....

Yeah we know. I don't think it falls on deaf ears, at least not some of us. But as much as I like what a by pass filter does and how well they work, (trust me, I'm an Amsoil user and they really push those filtration systems) most of us can't or won't put them on these classic cars. They either can't be fitted neatly and/or hidden on some cars where you don't want to look at something like that on a nicely restored car.
So we have to resort to frequent changes and try to keep things as clean as possible. |

This is great news. So many of these stories have a lousy outcome. Not with anything from Paul, just the hobby in general. You chose your builder wisely. Enjoy your car with traditional Pontiac power! That's plenty of HP to do it too!.

Glad everything worked out. I wanted Paul to build my motor but was just unable to overcome the logistics of an AZ/SC engine ship. I have found a great local builder that seems to have a fine attention to detail so hopefully I can throw up some numbers like you got. In a perfect world we could all get together and show off our cars and engines and do some real racing as well as bench racing.
