TrickFlow heads. A few teaser pictures

-
John, when was the last time you flowed any head, with any size valve....... that flowed 144@.100 lift?
Or anything even close to that?

I know I never have.
Nothing ever even close.

FWIW, 144cfm@.100 lift from a 2.30” valve is 134% of the C/D for the available curtain area.
I agree. That could be considered a .200 lift sb number.
 
Well that’s 60 horsepower in flow alone if it was in the usable range. And I’m betting the low cfm numbers were better too so it’s a win, win, win.
You were clear and correct.
The complete ingredients to the Influence on a/f or wet can be debated and looked into..but overall if you get more in within the range of cam..mo'powa!

I don't see any teaser photos, just cylinder heads that are all ground up and a hole in one of the ports.


And to “Dan the Man” I know you would buy a bigger head because that’s all you are capable of. The reason I posted a picture of a hole in a head is because we have members that do or are starting out porting their own heads. And mistake do happen so I want to show them you don’t have to panic. At almost 66 years old I spent around three hours teaching myself how to use a spool gun and fixed it. So if I can do it imagine what a “real welder” could do. People like you drive people that are willing to share some tech. So maybe grow up some and possibly learn something so you too could improve the site instead of hurting it. Have a great day.

Ok far right side column is after straightening out the common wall a little and tubing the bolt hole. I didn’t aggressively attack this area yet but will after I open it up to a 2.05 and hopefully a 2.08 valve. I gave the short-turn a little loving. (5 minutes max). You will see I lost cfm here and gained there. I feel this head is begging for a 2.08 valve. TrickFlow did such a good job of maximizing a 2.02 valve on this head.

Hey John, if you haven’t changed it yet, can you give me the throat % for the intake and exhaust on that head?

Playing with PipeMax and I’m getting numbers that don’t make sense, and I think it’s related to those %’s.

TIA


Sorry but I can’t right now. The second head is still assembled and I’m leaving the on on my bench so I can do some air speed testing. My plans were to jump on my black duster and get the transmission out so I can rebuild it last Monday. It didn’t happen so I gotta get on it this week. Please remind me later in the week.
 
How does the port “sound”? Do you find it getting a little more noisy the more you open it up?
So far, to my untrained eye it looks like TrickFlow pretty much maxed it out as-cast. To me that makes it an excellent value right out of the box.
 
Are you measuring air speed in the port, before and after? What I don't like about that head is how small the pinch area is compared to the short turn "area" and then the 2.02 valve. Kind of weird but if you run a large enough cam they'll make power.


These speed numbers are from an earlier post on a stock head.

Hope you are right i have trickflow heads going on my 340 should be dyno tested nexr few weeks will see how much better they are than the ede heads being replace

They did do an excellent job on these heads. I’m not sure why we aren’t seeing better running combos out there but I know you can’t run baby cams and street type converters and expect miracles. Ohhh port sounds great.

Did you change anything else on the combo? Just a straight head swap would be interesting. Any dyno numbers from ede head combo?

5 cfm. So which move hurt peak? the wall or the roughing of the ssr? Great thread. Thank you
 
I always enjoy reading though your porting threads, appreciate you taking the time and effort to document and explain what your doing.
Thanks for sharing!

Ditto!!! I have for certainly learn a thing or two. If fact, you helped save a set of heads for me just by your posts. Being able to do the work myself with nothing more than a quick PM for a tip and to make certain of what I was attempting to do was the way to do it helped in a huge way.
 
Peak cfm improved. Head started backing up after .700 which is common with a smaller valve with a maxed out port.

Nice #'s already, I suspect the work is leading up and wanting a larger valve.
