Based on that post my 7.342 length is correct
Is overspray on cylinder head ok?

so in your opinion this valve train is *also* a mess because of the pushrod angles?
My research of those pushrods said they were longer but if that is what they are you may be just fine.

Those look good. Somebody else made comments about those pushrods on the op 340
Here's oem pushrods from factory adjustable, ball/cup. Right around 7 1/2"
Solid or hyd lifters?

If there aren’t grooves in that shaft do NOT put them back on without putting grooves in them.
If the shafts aren’t killed already they will be. You absolutely, positively can not run those rockers with hydraulic lifters and no grooves.
There are grooves on back side of shaft

Outstanding. Can’t tell you how many junk shafts I’ve seen from not having grooves. Even with solid lifters they should be grooved. But you can get away without grooves with solid lifters but not with hydraulics.

Do not, do not listen to Dan DaMan that valve train is not a mess. Looks like a complete set of 273 rockets arms
Best thing to do is instead of taking pot shots at length, is use a checking push rod.
Call Smith Brother's and have a set made took a week to week and a half. Well worth the wait.

That shaft looks like it got hot and lacked oil.
Looks like scrap to me.
You've got to set it up and measure to get the right ones. Many factors to take into consideration.
You'd think that.....I put together a 340 and was planning on using the 273 stuff. After I was done measuring I needed pushrods approx. 7.1 inches long. Smith brothers was 4 weeks out so I just used the oem stamped stuff.

they do look a little galled up. hopefully that's just the photo... but with the glimpse of the cam in that other shot... i dunno man.
Are there notches on ends of shafts? Pics?
A little off topic here.......While I am thinking about it...
The WP bolts look new? You know about the driver side shallow timing cover hole correct? Too long of a bolt there and it goes through #1 cylinder. I believe it is the 2nd from the bottom IIRC.

Find out exactly what you HAVE first, before you pull the trigger on anything.
Good call Troy, man this sucks but I suggest a complete inspection piece by piece.
Can you catch any of those scores with a thumbnail? I don't think it'd hurt a thing to polish them up with some emery cloth and mineral spirits.
That's what I would do......$4500 for the engine PLUS a six pack.......
Just an aside.....My numbers matching 340 had std bearings on a .010 under factory crank. This was put together by an engine builder to boot...So it does happen.
Yeah i will clean those up a bit
.........And pop the end caps and clean them out.
