looking for a real fm3 demon 340 1971.
The only source I believe to be credible would be Galen Govier, at a cost of course. Then again he will only give you the breakdown for your specific vehicle, and yet I'm not sure if he himself has the data to do this, as he specializes in Hemi cars, B and E bodies.
Like the old saying goes "You gotta pay to learn" (so far unfotunately)
I understand what you are saying.
And I dont question for a moment your figures and statements about FM3.
Chrysler Power got it from somewhere.
The question does come to mind about Govier: If he is the only source for some type of specific information, how does one know it is for real?
In other words where is the verification of what he says?
Information is sort of like a toddler.
Once it is set loose one doesnt have control over were it goes.
Neil Bortz is fond of saying never believe anything he says or from the Internet unless:
A: You know it to be true.
Or
B: You can verify if from another source.
Perhaps that is hyperbole, but something to think about.
Like the old saying MIGHT go: If you dont learn, you will pay.
Im still learning, and paying.
