So don't get me wrong... I'm not trying to bash you, but please just take care before you start shooting from the hip about your new product. So not that "flow" is everything, but the flow numbers posted aren't even as good as a w8/w9, and barely better (if any) then an Indy 245RP. So be careful with your, Quote:
but ill bet this,You can make more power with my head out of the box than others ported and polish finished product!
comment.
It just makes it seem like you might not quite know what the benchmark is. A canted valve head that doesn't make any more power then a wedge head, isn't exactly going to sell like hotcakes...
Also... if you have a head to flow, why can't the pictures be posted? Something obviously exists in physical form...

Guys don't get caught in flow numbers. Port design and shape is a major part of making power. Just because one head flows more air than another does not mean it will make more power. I bet you a spread port head will make more power with comparable flow numbers. Just my
Why would a spread port layout make more power per CFM? We've done spread port heads for customers with good results. But, there's no inherent HP advantage over symmetrical or SB2/P7 port spacing. The original spread-port heads simply minimized the differences in the long and short intake ports of the much compromised BBC design. The big power was more a result of much raised ports, and reduced valve angles. They are still a compromise as compared to a symmetrical head. That probably plays into why there are no spread-port style heads in P/S or cup racing currently. Other than to benefit intake manifold packaging, I don't know why unlike intake ports would be desirable.

how much does a complete W9 set up like that run? Answer that and we will know what price he will have to shoot to beat.
Heads...... 750 on the bay. Rockers ( T&D ) 1,200.00 Intake .....new from Ma 425.00 Offset lifters 720.00 Porting.......I don't have the final bill yet , but the intake is getting done as I type and I'll know soon enough. Suffice to say it is in the couple grand + neighborhood with valve springs and assembly. My flow numbers are significantly better than those posted.......especially at low to mid lift. Now , those numbers are reputed to be out of the box , so it may flow monster numbers. But we're talking price here. So if it falls in the 3,500.00 neighborhood as a bolt on kit , it should be a heck of a deal. Very Indy like in that regard. I'll keep my eyes peeled , but I am locked into my current path and barring disaster or lottery winning , I hope to be done dropping coin on this scale for a while. But then again.............

I was just stating the fact that when you change valve layout from in-line wedge, to a canted head, you're going to need new valves....also, with the change in head/valve goemetry, you'll need a different camshaft to get the valve timing right. 318 poly and LA cams are not interchangeable which means possibly being stuck starting with a billet core ($$)

And lets not forget pistons. They will need a different valve relief cut in them to clear canted valve angle. Not a big deal but just more things to change, and im sure there isnt a performance "off shelf" piston so theres more expence. Unless im wrong here, and there is a set out there.

As been brought up in many past posts the mopar crowd is not into hardcore racing and doesn't want to spend the $$$ it takes to go this route. Good luck with this head hope it works out for ya I will stick with my w-9s. Well as long as yours does blow them off the map.

Let's not confuse hating with stating. I also welcome any new and cool developments for these little brutes. That being said........59 degree , 48 degree , 8.90 to 9.56 deck height , X , W-2 , 5 , 7 , 8 , 9 , P-5 , P-7 etc. etc. There is something to be said for a standard , and it has worked well for other manufacturers. This boutique block and head phenomena is a relatively recent development for all of them and MoPar just doesn't have the numbers to justify the tooling and development like Chevrolet and to a lesser extent , Ford. Face it , if we ( the collective we ) didn't get some perverse pleasure out of doing something different , we'd all be driving Camaros , Mustangs or God forbid , Novas. I'll be watching this deal as it progresses and wish the people behind it nothing but the best. But that doesn't change the reality or the nature of how things work. That isn't hating at all.
