Bad Valve Guides--- Warranty success / Failure

[ducpainter]

We'll check it out if I ever have to get inside the engine.   Hopefully not anytime soon, but I was watching them do some flow work on a Big Block Chevy head yesterday.  If I get in there, they'll help me do whatever I need to do.   Some pretty good guys work there. 

The engineer highly recommends these guys, they do damn good work.

They are known in Duc circles as Kibblewhite guides.

Goes to the same url that corndog posted.

I forgot to mention that that was the Kibblewhite site.

Yeah, Kibblewhite, from your link, was the name I was trying to dredge up.   Great catalog - just reading through it makes me want to build a motor.  

Thread drift - I was talking to a retired top fuel dragster driver the other day and he showed me a used piston.  Was very interesting, I don't know what I was expecting from a piston from a 1,000HP per cylinder engine, some sort of ultra high tech thing, but with the exception of the top ring groove it looked like a regular piston, and was even heavy and had long skirts.   He said he used to pay $45 each for them new when he was racing and when they were worn out  he could get $50 for them as souvenirs.

Bob, speaking of thread drift, this is a piston out of a 500" Top Alcohol Hemi, one that apparently, according to the crew chief, someone forgot to tighten the rod bolts.  Ouch.

Ouch is right, if I was the guy who forgot to tighten the rod bolts I think I'd be thinking about Hiri-kiri
