Re-restoration in progress for some vintage racing

I think he was referring to the candy bar.

Exactly what I was thinking.

With 30% less fat, who could argue?

 

[msell66]

Damn, thought I had it sold.

 

[Patrick Stapler]

Figuratively speaking...

Looks very nice!

After the Lake Garnett race weekend, I’ve removed the engine to check everything out.
After the rockers broke, the engine was still running fine on 7 so I’m hopeful that there won’t be any other damage.

What you obviously lack in driving skill you sure make up for in engine destruction abilities. Not just anyone can find completely new ways to break so many new engines.

It’s a learned specialty I’ve perfected over the years.

How could this happen ?
Have you overtighting those bolts ??
Does your springs binds under pressure ?
Pushrods too long ??
Manufacturer fault ?

Bad adjustement of the lash you should have on this particular cylinder ??

It's . What more do you need to know?

Hard to fault any set-up compatibility when just this one place saw the problem. Could be fatigue. He had run this same rocker set-up in countless previously destroyed engines. I think he is just highly skilled at breaking stuff.

It is very strange that this happened. I'll take it apart and check each part. Hopefully, it will tell the story of what and why those bolts failed. I've run that setup since around 2009 so maybe it is metal fatigue. Keep in mind from 2012 to this year, it just sat in the garage.
It was the best shaft rocker setup I could afford at the time. Now, I'll have Deb work extra hard for a much better brand!

On the bright side think of the money he saves on tires.

LOL

 

[Boom]

Always fun when stuff breaks. I had that happen to me this week too. I used Summits application finder instead of a caliper (lazy me) and wound up with a bearing that was like .06" too small.

I think I dodged the expensive bullet!

After initial disassembly, it looks like it really was a bolt head breaking off that started the carnage. After welding a nut to the studs, I was able to remove them. They were still tight and well sealed. No stripped threads and good bolts screwed right back in. No damage to the cam end of the lifters or the cam lobes.

My friend who had his 8 yr old motor let go sent me pics. He wins (or loses I guess).

That’s all from a broken valve spring!

 

[Horseplay]

By the looks of things I say your friend is a cheater. That's a roller cam set-up in that damaged block. And is that an aluminum head? Not exactly vintage!
