Re: Fixing the Jerky Solid Flat cam you probably have!

I have read about Bill Da Grump Jenkins using a machinist file and polishing cloth to treat his camshafts, and back in that time frame...70'S and 80's, 9000 rpm valve train control was a really big deal as the spring quality just was not there.... So you have to believe that he was doing this for a...

Re: Fixing the Jerky Solid Flat cam you probably have!

Here's an interesting thread about cams from here on Speedtalk from a number of years ago. Mike Jones and others are commenting on polishing/smoothing and its effect on the lobe: https://www.speed-talk.com/forum/viewtopic.php?f=1&t=9026&start=45 That's just it. When you start applying 240gr...

Re: HOW HOT IS A 426 TODAY?

The 426 Hemi design is the motor that most all top fuelers use, because it has proven to be the best design in the ultimate class where blowers and nitro are king. The Outdated? yes, for gasoline and moderate performance . But like others have said, it still shines in its' SS/Ah and SS/A class. The...

Re: Lightweight tool steel retainers

Hoffman, Did Godbold publish his thoughts or did you learn them through personal conversation? There is a Hot Rod article but also his Facebook page. Paraphrasing, but he pretty much said 99% of the people out there are better off with tool steel as opposed to titanium. Thanks. I don't have Faceboo...

Re: Lightweight tool steel retainers

So, lighter isn't always better. Ok, but what's the issue? Have you nailed down the WHY part of it yet, and would you be willing to say? We nail it down. It's the property of the material. I'm not a metallurgist, so I may not be saying it correctly. The structure of the Ti amplifies the harmonics o...

Re: SEMA and Fake Parts!

I guess that depends on the dollars your looking at, how you search it and your source. If you look at the bank bailouts alone you have trillions to wall street or this from Forbes puts cali tops. http://www.forbes.com/2010/03/19/bailout-states-obama-personal-finance-bailout-money.html That article...

Re: SEMA and Fake Parts!

Companies have been doing this forever. Read about Ciba Geigy (now BASF), Dupont, Union Carbide moving around their factories. Have a factory somewhere for 20-30 years, workers start getting sick, towns people get mad, pack up, rinse and repeat. This has been going on for a hundred years now. How m...

Re: SEMA and Fake Parts!

In case no one noticed, California is broke. Not just some counties. It's broke as a state. So in your thinking, taxes and legislation is a good thing? Unreal. Yep! They would be like Detroit if the Gov wasn't bailing them out with other states tax payer money. http://money.cnn.com/2013/07/18/news/...

Re: SEMA and Fake Parts!

That explains why California, with their high levels of legislation and taxation, would be one of the highest GDP countries of the world? When I was selling chemicals I would watch companies move from California to other areas in my territory (several western states). I recall one large company in ...

Re: SEMA and Fake Parts!

Businesses only leave if it makes them more money Isn't that the same reason why people leave old jobs for new ones? Yes. If you're in the private sector and you're not moving around every 5 years or so, then you're going to make a lot less money than you could otherwise. For the most part it is th...

Re: SEMA and Fake Parts!

Sorry Gary, but that's not how it works and that's not how people work. ? I'm confused, I have been doing it for 30 years and my family has done it for generations before me and I have neighbors and customers that have done the same for generations? Maybe you live in the sticks. But if you anywhere...

Re: SEMA and Fake Parts!

I'm not sure if your last part is pro union or not? I am not pro union in it's current form, it has become to much like our politician and favors those who control it vs the worker it was designed to help. I live in Texas and it has become less free than I prefer but I realized 12 years ago that li...
