Interesting Flow Data....(Long thread)

Jason
Texas Speed
I know your fired up but I dont wan't a "drama war" on THIS thread.
Take it to PM's with Jason or leave it all publically in the other PRC thread. I want to keep this thread clear from BS and as informational as possible.
Thanks alot...

I think I need a vacation....

Had the oppotunity to evaluate another cylinder head of late ("W")....finally getting around to posting some info. This was a ported 243 casting (LS6) and the numbers were very good overall. Not as large as some of others tested here, yet still put up fairly solid numbers across the board. Don't know what "STG" it was but there was certainly alot of finish work evident and I can tell you it wasn't one of the most affordable options on the market (no surprise). Overall, one of the better performers that I have seen.
Thanks guys....

The Best V8 Stories One Small Block at Time
I think Jay's point was that he wanted Tony to test them as an independent and compare his heads to the others using the same controled variables and not as a test of his competence or value of his finished, tested work. It was for us to see and not to get numbers he didn't already know. I see he was openly saying to the forum, "I'm not afraid to get my work in on this test against your product" and I commend him for that. If he was being 'shady' he may have opted for the telephone.

I am totally confused here.. What exactly are you talking about? That post is like a month or so old.. Explain what you are tryin to say here..
As an FYI it sounds like a valvetrain control issue but that is hard to swallow with a solid roller. An engine that TQ peaks as late as yours (as it should) ought to make peak HP in the 6700-6900 area. Although if it did you wouldnt have posted a problem....LOL
Try to start a seperate thread strictly related to your power issues and include more information including a dyno graph if possible. Plenty of people on the board will probably throw in their .02....perhaps one of them will hit on something you haven't.
Good luck,

)Just flowed a ported 6.0 litre (Head "X")....The intake numbers in the matrix were extremely stout (360 CFM!) and I was looking foward to the opportunity to test them (turns out he was local).
The blue pill tasted especially bitter in this case, but the customer now knows he's needing something different in the "real world" to put up anywhere close to the power he aspires to make. Actually he was quite the sport about it and was more pleased to find out now then later (after spending countless hours trying to find a bunch of missing horsepower based on "optimistic" cylinder head flow). If your reading this it was good spending some time with you today....let me know about the 225's
Regards,
Tony
