HolBrook Racing Engines Makes History!...

No disrespect to anyone but the part # is listed in the guide . I know Holbrook can read and the NHRA tech people could read the number on the head. I think we can all agree on that . Call it what you want but it was the wrong casting number for the head .

The Fact is that Holbrook did use the wrong head's when the numbers were clearly visible to everyone and went 1500 miles to try and set a national record with the wrong numbers on the heads. He did not get tossed , got no HP and the AHFS failed

Charlie, call me and I will give you someone who will tell you that people have set national records at opens and been sealed up to tear down later , got the hp, when they torn down they failed and the HP stayed on . This person is well known and a long time racer 30 plus years

The only point I'm trying to make is that there should not be a loop hole in setting a national record that circumvent's the AHFS system

Hats off to Jim Collins and company for checking those casting numbers

Let's try this for the sake of argument. What if all of the 50 2013 Cobra Jets and all of the 5.0 motors that Ford Motorsport sold had the same casting #'s that Chris had on his heads? AND what if after the run Chris was preoccupied trying to remember if he put ice in the beer cooler for the evening festivities and forgot to stop at the scales. This could be a real head scratcher for some of you guys. Get your facts before you try to expert this situation.

Why don't you inform me of the facts since your in the know. How about this, he did not put his glasses on and could not read the numbers on the heads


Hey why dont you use your real name ? do you remember it ?

You seem to have all the answers, so you should know my name. You should also know Chris doesn't wear glasses. Turn on spell check and check your grammar too!

Just a little story about Ford and NHRA engine blueprint sheets. Back in 2006, I was trying to get Ford to classify my 2003 Mustang Cobra for NHRA. I sent all part number's to Ford, so they could verify the numbers and send them to NHRA. NHRA put it in the guides and said it was legal and ready to go. For some reason something told me to check the guides and make sure the numbers all matched!! Well low and behold Ford had a number or letter missing, can't remember which one. And, they had a letter that didn't belong. SO it took me calling Jesse Kershaw, who finally got the right numbers to NHRA. It can happen.

It wouldn't surprise me about NHRA having the wrong numbers. They had goofed up on a few things on the 2013s in the guide that were incorrect. Jesse had to contact them to get those items corrected. That is the unfortunate part of adding a new car to a guide(new or old combo). It usually takes a little bit to get it straightened out.

The heads that the 2013 CJ uses are the stock 2012-2013 Boss 302 heads which are a different casting number then the standard 2011-2013 GT heads because it uses different grade of aluminum and a few other differences. The only place to get the heads is off a wrecked car or buy from an Ford Racing Performance Parts dealer for either of the heads. The 2012 5.0 Cobra Jet used the standard GT heads.

Maybe Ford did a revision to the heads and there by creating a different casting number on the later Boss 302 heads and the information wasn't transferred to Ford Racing/NHRA or the NHRA simply goofed up when putting it into the guide(which has happened on multiple occasions). There has been people get bounced for part infractions that were 100% has the car was delivered which really is a tough situation.

To clear it up, the heads Chris was running should have been submitted to NHRA by Ford Racing. Whether it was a typing error or a missed casting number I'm not sure, but it has been updated. There is no performance advantage, just a clerical mistake that unfortunately wasn't caught prior to a teardown. We have now submitted all known casting numbers that are currently available and any superseded casting numbers expected to be available for the 5.0L through 2013 calendar year.

The Cobra Jet has been the most torn-down vehicle make/model over the last 4 years. With success this is expected. In the vast majority of cases our racers pass easily. There have been some growing pains in understanding how NHRA wants the specifications and their range of allowable tolerances and we have learned and improved our process along the way. Continual improvement is in our DNA for the Cobra Jet.

Beyond Cobra Jet we have had many corrections to NHRA technical information to help other racers, from pushrod intake manifolds to accepted aftermarket replacement parts. Overall we've been very successful in helping the racer.

That said, we are not infallible and we do always recommend that if you're going into the engine that you double check the casting numbers. If there is an issue we are quick to react and NHRA has been very responsive to our updates. We've sent in enough parts for confirmation that there might eventually be a whole car in their Indy office!

As anyone who has gone through a record teardown can attest, no one goes in thinking they are not legal, and no matter what the cause it's a bummer to not pass. In this case I already apologized to Chris for our oversight. I can guarantee that we are adding another check to our submission process to keep this from happening, and I'm sure Chris will double check the casting numbers on the NHRA site in the future as well. It's an unfortunate event when anyone fails tech on an oversight or technicality. It gives me no pleasure to see any racer suffer from that consequence and we do take it seriously.

For those of you that have delivered numerous Ford records over the last few years I thank you for your diligence and dedication. I can tell you that we are committed to continuing our diligence and dedication to keep you in the winners circle as best we can!
