Here's a link to Eric's video discussing the details of the new cylinder head he's helping Promaxx develop.
Looks to be promising. These should work very well for a stock displacement 440 or 400 Big Block. I'd even be tempted to try them on my 505 vs the TF270's I've been eyeballing,just for the fact that he's keeping them much closer the the "Standard Port" size. I could retain all my current top end. Thoughts ?

Chinese copy of the TF240.

Yes it is. helped develop oh that is rich.....

Yes, he fully discloses its a Chinese head. One of the first things he says. If you watch the video, you'd learn he's developing it past where it's at " as cast". The prototype port he's developed is flowing in the low 340 cfm range @.700. Pretty impressive considering it's more of a "Standard port" size on the intake.

Another head in an already crowded market....

Crowded ??.. certainly not vs. Anything Chevy.

It’s a blatant copy of the Trick Flow TF240………. that’s made in China.

I knew they were coming, as I saw pictures of piles of them stacked up at the foundry a few months ago.

I understand your point.. and you're not wrong.. But I think that's the world we live in nowadays. Leo Fender Released the Stratocaster in 1954. The Stratocaster is an American Icon, but it's been tweeked, refined and improved upon "Blatantly copied" for the last 70 years by any multitude of manufacturers. If someone engineers a great design, it's gonna get copied. That's business.. and that's capitalism. I just thought the numbers Winegartner massaged out of it within the confines of a standard port were impressive. Just wanted to share. I like Winegartner too.. he's a no nonsense honest guy.

They are most likely made by CFL Engine Parts Manufactory

There would be 20 oe more Chevy guys to every Mopar guy, it's a crowded market

Yes, but there is also 20 more cylinder head options for each one of those Chevy guys.

How many offerings for the Mopar crowd from AFR ? . Zero, How many from Dart?. Zero, How many from Profiler ?. Zero.. etc.etc.

See my point ?

Because fewer people are buying them, why would these companies throw money away to develop, manufacture and offer them? They'll sell 100 pairs of LS heads to a pair of Mopar heads.

How many different brands of what are essentially the same outdated design of head do you need?

So, you're saying it's not worth improving Big Block Mopar head design? Because it's an old design? That statement makes no sense.

How much fundamental difference is there in a Trickflow 240, Indy EZ, Edelbrock RPM head from the factory head?

How many differences fundamentally ?? Ok.. The most glaring difference.. ALUMINUM !! On average 25lbs lighter per head. The chambers are vastly redesigned to improve combustion and resist detonation. Valves are significantly lager and typically Stainless Steel for durability. Not to mention the larger intake runners!!.. blind accessory holes.. etc.. the list goes on and on. Multiple fundamental differences.

And based on how I see Promaxx pricing their other Project X series heads, it will still make more sense to buy the original Trick Flows => Promaxx Project X Series

In architecture? Very little, since they are "stock replacement" heads with standard valve location & angles and standard-offset rockers (not including the MW-port Indy EZs)

In implementation? They each have their own approach to runner design / volume / chamber design / valve sizes

Would be nice to see someone come up with a canted valve head designed to fit on a BB mopar or a more affordable version of the Predator head instead of these dinosaur inflated small block style wedge heads.

AG.

Agreed. If priced similarly I would definitely lean toward the Trickflows as well. Better casting and QC in most circumstances. I am impressed with Winegartner's numbers though.

They are NOT improving ANYTHING! Just another Chinese knock off of an already produced head. It's another unnecessary choice in an overcrowded market. I guess unless you are to broke to buy the American version in which case maybe a look at lifes decisions might be in order.
