no offense taken,,, ive just seen this often in my 20 years of doing heads,, everybody in the country,, big name or little cant get close to your numbers,, usually ports are down so far from claimed numbers they arent what the pros or usually people get,, but maybe youre the guy who disproves that
p-5 heads dont flow that much, an inline head with pushrods where they need to be,,,, hard to believe you could get those numbers,,, id like to see it,, if they flowed those numbers,, id do that job for free

Actually being developed for a 2x4 468 on e-85....4.185 4.250.....we will see...
That's alot of stroke......
Big bore, unshroud the valve and a 4in stroke will rpm with manageable piston speeds over 9000. RPM is horsepower and ET.
Turn that thing and use the converter and gear for mechanical leverage.
At least that's how I like em'.

I didn't think there was enough actual cyinder head to get those numbers, but what do I know.
I talked to Matt at MBE.....he thinks the P5 will get there. That is one serious head.

the low and mid lift numbers are in your valve, valve job angles, and chamber
im sure you have a 55 degree seat or steeper on that to get those numbers,, with hard coating the valves ive run as much as 60 degree seats,, maybe you have that,,, which hurts low lift bad...
its just your claims are off the charts,, nobody is trying to say you arent qualified to port a head or whatever,, its just unheard of to beable to get a port in that head,, that big,, to flow that amount of air
and to the guy who asked about how much you moved the guides,, or how big of a valve,, he must not have read that earlier you said you didnt do any of that,, the head is mechanically as recieved from mopar..
im doing a d-3 ford program with a 2.250 int valve on a 4.165 bore for a nhra comp project,,, if i get the kind of numbers you claim out of a better designed head,, ill be great!!! 373 inches,, 450cfm,, should be enough to make 1040 hp at 9500rpm
