Here is a summary, but it really doesn't do this write up justice. A few people have commented that this is the best write up so far.

We have a new format that uses hyperlinks to click on to take you directly to a certain section
This is the largest write up at 129 pages
Cylinder head port volumes and combustion chamber sizes were measured on some of the heads
We now have EGT data on almost every dyno pull in this write up
Batten cylinder head testing
Stroker engine testing
Lot's of stroker engine data PDD ported heads on the stroker engine
Methanol on the stroker engine
Small block Olds testing
Lots of 1.7 rocker ratio information
Camshaft, intake manifold and spacer testing (5 roller camshafts, 3 intakes with each camshaft, and spacers) This is really pretty significant.

I will be back in MI the week before homecoming. I'm hoping to arrive in MI on 6/15 and start working on 6/16. However, I have a lot of stuff I need to finish up here in FL (and we are going on a two week vacation to Alaska later this week) and I'm not sure I'll be able to leave on 6/14 as I'd like to (I'm driving up with parts I'm going to try to sell at Homecoming. I will probably fly home on the morning of 6/24.

Jerry - You did a fantastic job of creating this document via manual insertion of document links. You spent significant time performing these operations and KUDOS to you!

SUGGESTION: Since you asked in the 1st section (Navigating This Document: Using Internal Links) for comments, I'll add mine.

I can't validate what word processing s/w you employed to create the document, but there's an easier method to create this type document which might serve you well as you move forward with edits, insertions, etc. There are many word processing s/w programs available, which you employed, I can't validate; but let me move forward with my suggestion since most word processing s/w provides the ability to create a living/breathing document via the creation of a TOC (Table Of Contents) based upon "Headings". You'll just need to familiarize yourself with how to create a TOC employing Headings. In this manner, all your Headings & page numbers are automatically inserted into an automatically generated TOC. Employing the TOC (Headings) feature allows you to update the document as if it were a living/breathing work of art and reduces your manual creation of links on the various pages of your document. NOTE: You can still create an automatically generated TOC in your current document (recommended) if you choose to do so. Perhaps an easy method might be to make another "copy" of this document (you likely have several) and practice on a copy of this document.

I'll provide guidance at any time should you choose to proceed in this direction. It's a huge time saver especially for a living/breathing document which will likely contain numerous edits/changes/insertions/deletions moving forward. It would be far too lengthy for me to explain in text. Instead, I'll provide you a fairly well put together video of a YouTube Microsoft Word tutorial you can review at your discretion. Again, great job on the document - I know you spent significant time creating this document but there's a faster, easier method. Feel free to send me a PM should you have questions. Enjoy Alaska.

This video is germane to Microsoft Word, however most word processing programs/applications provide this ability.

 

I normally treat YouTube as the AntiChrist, it has been proven to make people dumber (seriously). But in this case I will find time to watch it as it was a LOT of effort making this document. I am using MS Word (not sure of the version but at least 2019 or newer).

I still plan to make a master document that goes through all of this information in totally different format, with all the dyno graphs and data attached, so this will be handy for that as well..

I took your .pdf document, converted it back to Word, then created a very simple TOC simply creating Headings. Took me ten minutes. As said, you get in a bind, have questions send me a PM.

This what the new TOC looks like in Word before changing it into .pdf format. Simple stuff, really. I DID NOT review for simple errors, only a simple demonstration how to create a TOC employing Headings. You're doing excellent work.

It's just a Snipping Tool image not the page from the actual document.

 

I KNOW how much work this took for you, believe me, I KNOW. I've been creating hundreds of documents with thousands of pages for nearly 30 years.

Here's another little trick should you care to tweak your limits. When you create page numbers for each page contained w/in a document, there is a setting you can employ...similar to inserting/creating a footnote. If you employ the page function (at the bottom of a page, side, top, doesn't matter), when the TOC is created an AUTOMATIC link is created in the TOC which, when a user/reader clicks on the page number it will automatically jump to that page number. Stuff, eh?

 

Jerry….this is outstanding work you have done and the report is terrific! Lots of great information for us building performance based Oldsmobile engines like myself! I have read and studied every page….including your previous test results! On my second reading now. Sounds like you had to work through a load of challenges and barriers….and I thought that only happened to me 😂😂😂.

I am getting ready to start on my 70 442 455 engine so the timing is perfect for me.

One question….did you run the 11.2 to 11.8 CR combos on 93 octane pump fuel?

I have successfully run an 11.0:1 CR 400 CID sbc in our 67 Camaro on 93 octane pump fuel with overdrive transmission and 3.31:1 gear….and it’s fine. Next engine (almost done) will be 11.25:1 with a smaller cam…..hopefully it will be ok as well. Tighter quench this time.

Thank you so much for taking on such a massive endeavor…. This will be a huge help to the performance side of our Oldsmobile hobby going forward.

Lots of good info here as usual Jerry, well done!!
If you want to talk about the distribution issue in the manifolds, let me know. I’ve done some testing on that myself as well.

 

We did. The engine was knocking at low RPM (below about 3000 rpm). We also probably had the engine a bit lean as well (around 13.5) and at lower RPM it was leaner. I think we took a set of rod bearings out because of this. When it's back running I will richen it up and take some timing out. We will also use the thicker head gaskets, just to prevent failure.

The best Olds performance info in one place, Thank You Jerry!
