Let's talk G3 hemi cams

Well, I did feel a little canceled... But, I do accept what you had to say.
It's been a year since I've seen the episode I'm about to refer to.. I'm probably going to have to find it..
One time in particular, Holdener did a mopar, phord, shivi SB shootout, of sorts.
First off, there was merely a cursory overview of the heads being used. (were they flow tested?? were they even in the same realm from each other?) the phord got an aluminum head (for sure) and I think (?) the mopar got a OE Mag head.
No stipulation as to headers used.. same config? Cam's, who knows. I think one of them had a 4"crank and it wasn't the mopar!
So, I wondered, what ARE we testing here ???? it certainly wasn't scientific. I had an overwhelming suspicion Holdener threw together a bunch of unrelated dyno runs, just to have something to post.
You seem to be one of the smarter of the FABO bunch (judging from past interactions), does any of that scan?
Not only that, he only shows the curves. I want to see the data. Was the BSFC's way off on one of the tests? Or the EGT's for that matter. it's all too watered down for my tastes.
Now because I can't see that, how can I have any confidence in the test?
Here's the deal, I'm 58, I've seen a lot of crap passed off as reliable info. Running a flowbench and using one as a development tool, are two different solar systems. It is very complex.
Someone with true expertise simply have a different way of explaining things.. I like Holdener as a person. seems to be an ok guy, but the lack of complexity is a flag for me.
If someone is going to perform a (legitimate) shootout, those heads BETTER be damn near equal. Would you have it any other way, if it was your motor on the pump?

Lastly, to what end??? was there a valuable service provided? If a scientific instrument, like a dyno was used, supply the scientific data !
In my personal journey on cars, dating back to the late 70's, I absorbed as much info as I could. But I got to the point I realized some, or much of the stuff I was absorbing was total horseshit. One sided publications fudging dyno curves to regale their readers and pump the ego's of the editors.
I'm interested in the truth!
If I gotta eat crow now and then.. I would rather do that, then remain a fool.


I know exactly where you’re coming from and I feel pretty close to the same way about almost all of the tv shows and internet stuff out there. They seem to only only show information relevant to their target demographic. Who can blame them really. I’d like more data from about 99% of what I watch. You’re also correct that content seems to be king in the you tube world, even if the content is crap it’s still content and that’s what they get payed for. I’ve seen and am familiar with the episode you're referencing above and I think he dumbed it down purposely to better represent what is actually out there running around in every day cars. Of course he could have made all the heads the same, the cams the same, compression etc, but then really they’d all make the same power, or damn close to it. I don’t know, I guess I get both sides of the argument, make them identical so the test is scientifically valid, but also don’t go to great lengths to make them identical for a more accurate representation of what’s in my Mopar and my neighbors Chevy.
