I've got a few things going on in the shop right now so I haven't had a chance to scrutinize these things too much, but my first impression is that the overall fit & finish, and presentation is pretty nice. Over the next few days I'll try and get some measurements on them, but for today I only had a chance to put one on the bench and see what kind of numbers it put up.

Bore- 4.375
Test pressure- 28"
Intake tested with a radius plate, exhaust tested with and without a flow tube.
Exhaust flow tube diameter- 2"

Lift-----in/ex--ex w-tube
.100--71.6/52.9----52.9
.200-156.1/116.5--125.2
.300-229.3/163.6--174.8
.400-274.8/192.7--213.2
.450-290.5/202.6--226.1
.500-302.9/209.2--238.0
.550-311.1/215.0--245.7
.600-316.0/220.8--251.5
.650-317.9/222.7--254.2
.700-319.7/224.6--259.2
.750-321.6/226.5--261.1

Nice to see a head out of the box with numbers that continue to climb and not back up like most do. Looking forward to getting a set of these. Thanks for posting.

cool

That's pretty stout for an OOB standard-type intake port. How do the #s compare to the MCH CNC Edelbrock (Stealth?) you tested?

And another example of a stubby exhaust port that LOVES an extension added on to it.

Intake numbers are about 5% better than the last set of ported Edelbrock heads I had. The exhaust is roughly the same.

Thank you for the results & thank you for showing what was used to test the intake port & not using clay.
Intake tested with a radius plate

I ported a set of rpm`s years ago on Pettis`s flow bench that went 327-224 iirc w/the stock 2.14 intake valve BUT, if the meats there and someone either has a cnc program that will work w/these or can program, then they`d be really good for the intermediate power zone and a Max wedge could possibly really shine.......

Great info, (And Great to 'see' you, Fast)

Well there you go, 5-10 years ago guys who needed a "perfect" 650 horse capable head for their 500" B/RB strokers would have to buy a set of Eddie's and have them CNC'd or Hand ported, just to get about 95% of what we now have "off the shelf".

I really like the .400 lift numbers, mid lift is so critical for keeping the cylinders packed = Awesome torque. The non-stalling .500-.650 numbers look great for making big power at a still safe and moderate RPM ceiling. 290 at .450 lift is really exceptional IMHO, that's about PEAK flow for an out of the Box Edelbrock IIRC. Look perfect for a street-strip 10.5:1 440-451 4 speed and especially a 470"-520" Automatic.

Seems like a Near-Perfect gap filler, Standard 906 port size, anybody wanting/needing more would step-up from there to a Max Wedge. I've always liked the Trick flow finish quality, usually just want to upgrade the Locks/retainers and usually a quick 'true-up' of the as delivered VJ and they can be good-to-go compared to what I'd say to most other out-of-the-box head MFGs. I guess the main 'off the shelf' competition for these would be the EZ's but I'll bet the TF fit and finish is better.

I was planning on buying the std. port 440EZs for the 463 i'm putting together, but may now wait to see some more flow numbers on the Trick Flows.
Decisions, decisions

Nice to see a head right out of the box w/ comparable flow to a ported Edelbrock/Stealth/Sidewinder.

Ummm... I think you mean flow bench, not dyno.

More flow tests won't change how the heads work; I'll be interested in how they perform on an engine.

The flow numbers along with the modern combustion chamber should really make this head worth looking at. Even if the ported eddy matches the flow it should still be at a disadvantage. Can't wait to see some results in running cars. Thanks for the info Dwayne.

Since I don't know anything about a wedge why don't you guys enlighten me. Does this mean you use a bigger cam? I don't like rollers. Would a .590 lift purple shaft work well with these in a 512 BB? Thanks.

Brad, there was a post about Stealth head flow numbers a few weeks ago, I posted the numbers I got from the MCH CNC Stealth there.

Interesting they almost match a stock victor. I wonder what sort of things the head porting wizards will be able to do with these things.

I think the only standard port head that tops these As-delivered were the old Chapman Stage VI 260 (which I think JohnRR sent to Dwayne the same time I sent my Chap 265 MW's) And the Chapmans were Raised ports and long valve heads that need special rocker gear. I think they went 360 up around .600-.650, may still be in the Moparts archives. Not sure they were any better than these at .400-.450 though.

I'll have dyno numbers in a few weeks.
