wrong spec submitted by MOPAR
 

The reason for Dave Thomas's DQ this weekend

MOPAR engineering measures the valves differently than NHRA

A new TI sheet is being submitted

He passed tech to set the stock record and we passed tech at Fontana

I don't know - seems to me - you grab a set of veneers and measure it - some things seem simple

Dave told me he has a blue print from MOPAR on how it is measured - sorry us old school guys are just not up to date


Too bad for Dave - no record - loss of travel costs - loss of entry fee - not to mention him being besmirched
(be·smirch: 1.Damage the reputation of (someone or something) in the opinion of others)

Watch out new COPOs it has happend to the other two brands

Re: wrong spec submitted by MOPAR
 

It can happen to anybody, especially with a "new" car and depending on the manufacturer for the correct info. Not intentional by any stretch of the imagination.

What were they measuring? Head dia., overall length, tip length or what? Can't imagine anybody measuring a valve head differently??? Inquiring minds want to know. Any hints or is it hush hush??

Just wondering........

Unfortunately, most people don't care about whose fault it was or why it happened. To them "You got bounced in teardown" or worse yet "You got caught cheating"

Re: wrong spec submitted by MOPAR
 

Dave was not cheating - It was MOPAR's mistake

It was the head (big end) they were measuring - as I said - how in the f... could MOPAR possibly screw that up or need a blueprint

I am sure I will hear about being so hard on MOPAR - if an engine builder made the same mistake - there would be hell to pay - not just - as one person put it on this thread "***** happens"

If memory serves, the same thing happened recently to Charlie Downing. What's with these corporate engineers? Give them a fancy name and they forget the simple stuff? Jim

As I remember it happened to Ford a few times
1966 or 1967 427 pistons
1st year of new CJ's pistons
The next year it was something else
Charley Bobs deal
It happens when people don't know how NHRA does things. They don't do everything wright but they do have the final call!

Re: wrong spec submitted by MOPAR
 

What was the deal with Irv's deal?

Re: wrong spec submitted by MOPAR
 

A professional stock eliminator engine builder would have measured the valve the right way and in Irvin's case with no number on top of the piston would have called California for clarification. You can't assume these motors are going to be right when you get them.

Gregg that was the same thing Curt Lashure told me a few years ago after I set a record at Atco. The piston dish was .375 off.
He explained that some aftermarket manufacturers would submit a piston and then build a different piston with the same numbers for a customer.
After listening to the stump speech for what seemed like an eternity. I explained (or tried to for about the 3rd time) that the pistons in question were not stocker pistons. But stock assembly line pistons, that came in ever 2.5 turbo mopar ever built (a couple of million).
When I explained that a .375 difference would make any diesel proud. He looked at me with a bewildered look.
The outcome was they let california make the call. I was not allowed to race that weekend and was never offered a refund. Even though I was totally legal (as per california).
Another go round was when they tossed me for having my pistons to far down the bore.
He told me it could be an advantage allowing more piston to valve. But then told me I could run any thickness head gasket.
I miss Gregg X's common sense.
