....bum....bum....buuummmmm....... join us next week on another episode of Unsolved mysteries.....
I knew that @Selahdoor would make this thread interesting! Surfacing the top doesn't make any sense to me either.
This we can be sure of though:
Eric Clapton and Bob Marley, shot the sheriff.
This we'll have to wonder:
Who screwed up this serial number?
I agree, these not lookin like the codes on my 6.9 block and 7.3 engine. If I recall correctly, is 7.3D for the beginning, right?What you didn't mention is the number size. The restamped numbers are too large to be factory numbers. Our engines' serial numbers also didn't start out as "7.3L".
You are correct. I didn't mention it.What you didn't mention is the number size. The restamped numbers are too large to be factory numbers. Our engines' serial numbers also didn't start out as "7.3L".
Maybe, but I can't think of a single reason to surface the block in that spot.
Maybe they surfaced the block,

Gentlemen, gentlemen.... if...that block had been decked and/or the heads had been surfaced...it would have changed their location in relationship to one another...and on a 'V' engine...the intake ports and bolt holes are not going to line up like an untouched factory block, heads, and intake setup until you mill the top surface to lower things so that they will line up correctly...Someone removed the factory number and restamped a new one.
Generally yes. 6.9 or 7.3 and then DU2U is how most of them start. TU2U is a Turbo block. Of course then you can also have DM2U with either 6.9 or 7.3 in front for an International application.If I recall correctly, is 7.3D for the beginning, right?
Well there's your answer. It's not a Turbo block because, as far as I know, all Turbo blocks had a 1/4"NPT port there.the oil port by the filter housing is 1/4 and has a goofy reducer to 1/8th for a plug.
Don't worry. It's NOT as big of a deal as most people on here make it out to be. These are very simple engines, without a lot of wiring to disconnect. Yes they are big and they are heavy, but it's not like you're trying to use a come along or something.Now the big ordeal will be installing it. I've pulled 1 engine and it was in a car. He's done this before with a straight six. He's got a huge engine hoist also that looks 70 years old so it might not bend like the hobo freight ones.
This will be stretching the old fuzzy memory, but I don't think so. If you surface the decks on the block enough for the intake bolt holes to not line up, the solution is to surface the mating surfaces of the intake manifold do that it will sit lower. It's not the "lower" part that gives issues with intake alignment, but it's the "narrower" part. The holes (and ports) on the heads do sit lower, but they also sit closer together. One more thing, if someone surfaces the decks enough that there's intake alignment issues, there will also be piston to valve clearance issues on our engines.Gentlemen, gentlemen.... if...that block had been decked and/or the heads had been surfaced...it would have changed their location in relationship to one another...and on a 'V' engine...the intake ports and bolt holes are not going to line up like an untouched factory block, heads, and intake setup until you mill the top surface to lower things so that they will line up correctly...

This is why I tap into the 'Brain Trust' that is available on here...a good answer..!! Thanks for explaining all of that....One more thing, if someone surfaces the decks enough that there's intake alignment issues, there will also be piston to valve clearance issues on our engines.
