The checking rods will bend at the thread with the springs on that motor I reckon I would put light ones in to make sure its right and the rockers are running in the centre of the valve

The object is not to have it run in the center of the valve . The location on the valve will be whatever it will be after the proper geometry is established . If your lucky it will be in the center.

He doesn't need to turn the engine over to do it for his particular app.

Yeah but he has shaft rockers  not stud you cant alter the height of the rocker with out shimming them on the head, all he can do is get the rod the correct length, its not the same thing, can use the same method but you only have one thing to change.

Yeah the shaft mount certainly does make it a bit harder and i would have to try to explain how to do it which might be a bit difficult . im just trying to think of a way to simplify it for him so he doesnt give up . virtually no one other than engine builders check this.

There are a zillion engines in the us with less than optimal geometry but they still run fine . obviously they are usually giving a little power away but based on his comments, he is not trying to eek out every ounce of hp and i dont want him to give up so im trying to figure a way he can get them reasonably close himself . one way would be to buy 3 different length push rods and narrow it down from there . that wouldn't cost him too much.

He's already pulled off a miracle doing all this without having ever even changed a spark plug before so i would like to see him finish it himself.  :bolt:

It is Easter I guess a time for miracles as the story goes. When it runs and lasts longer then last time I'll call consider it a miracle.

Oh, I wasn't expecting it to actually run. I just figured it would be a success if he only had two or three parts left over. :lmao:

I like to refer to them as "spares"

What photos of the rods do you want?

I put a photo up, is it not clear enough ?

Just go buy a set of checking rods, or make one, you can cut a rod and tap the ends, put a cut down screw in the center so you can make it shorter or longer

XLNT

POST A PHOTO OF YOUR CAM CARDS . THEY SHOULD HAVE GIVEN YOU ONE WITH THE $18,000.000 ENGINE . IF YOU DONT HAVE THAT ONE I WILL CALL SNAUSAGE MONDAY.

the top photo goes to the rocker but it looks like they may have had them in upside down  :lmao:

the idiots must have put a reduced base circle cam in it.  :thud:

these are common base circle sizes, however, these sizes can vary depending on lobe lift.

std base circle ........... 1.340
reduced base circle .... 1.260
difference .................. .080

I will call the cam mfgs Monday, and if i can get the base circle numbers, you should be just fine if you get push rods that are shorter by the amount of difference there is in base circles between the two cams and then the potential tragedy will be averted . You can Ebay yours to get some money back.  :toetapping:

The closest ones are 6.875 which is fine . I would get the ball end type like you have if possible.

Here's standard end rods . You need .080 wall.

you can get push rods here.

manley .080 wall swedged end or crow .110 wall if they have a swedged end . .110 wall is a little better but you can't use ones that have a ball welded to the end.

So as this stage it's more than likely the push rods are too long, yeah ?

i would not do anything yet . i will check on our monday with the cam mfgs . if i get the base circle info, there is no need to even mess with it . it ran before so it will run again even if the geometry isn't flawless.

i have had to turn an engine over with a rod checker before with regular springs and nothing happened to it but as shaun mentioned, your springs may damage it.
