Nice build. Were the deck heights on each cylinder the same?

This is a very nice build! Also all the photos and info are great as I will be rebuilding my engine soon too. Thanks!

What oil pump did you use btw?

Interesting.. never had a strud strip like that before....

I see you have those vertical marks in your barrels...

I discovered vertical marks in my cylinders caused by wrong size oil rings during a rebuild. It looked exactly like what is showing in your pictures. I ended up pulling the cylinders off and deglazing them, I could not remove the vertical lines completely. After installing different rings I ended up with 5% leakdown after break in.

I think that your oil rings aren’t right.

Is your cam timing in the ballpark? If not, set that first.

Do you mean that you were rotating the engine anti clockwise?
Just trying to understand.
I think the Dempsey book told me not to do that at this point.

I have really enjoyed following your build thus far.

that accuracy is pretty good. The engine won't be able to tell ;)

I think OCD is a healthy quality for this part of the build.. I take vids of my cam timing.. here's one I did recently.. https://youtu.be/orQf6tUtC_s?si=iAY1miMHax-9iC29&t=565

Interesting question.
The billet cam blanks are all the same. They just grind the journals down from 49mm to 47mm.
What makes this interesting is that most if not all 77 cam tower are 4 journal.
The casting are the same as the casting used for 78 SC. The difference is the cam bore is smaller (47mm vs 49mm) and the unused journal is not drilled for oiling.
To be clear, the 77, 2.7 engine uses a 3 journal cam but the housing has 4 journals.
The journal that would be free (unused) with a 3 journal cam is not drilled for oiling. If it was drilled there would be a loss of oil pressure do to the missing cam journal.
These cam towers (77 2.7) are cool because you can drill the housing to make it a 4 journal housing (good for high RPM/racing motors). In fact, if you use a 4 journal cam in a 77 cam tower you have to drill it for oiling or the cam will seize in the housing do to lack of oiling.
We cam convert them for you or you can drill and plug them yourself.
The way you can tell if you have a 47mm 4 journal cam tower is to count them or look to see if the cam tower has one un-drilled casting and one drilled.

Yes, we can convert them for you.
Your cam towers look great but we have a complete restoration service for those who want it.
We can also convert 3 and 4 journal 47mm cam towers to 49mm.
After extensive deflection testing we have great confidence in the ability to use 3 journal cam housings on larger engines. The 49mm cams are incredibly stout.
That is not to say you should/can use 47mm cams on 3.0+ engines.
They don't work well.
