Dyno #'s with Trickflow Heads

-
So to get my build back on track and get the best bang for my buck. Whats my best option, easiest way to bump up compression as I really don't want to stroke the motor. I like the little 340. Thinner head gaskets?

Yes, same dyno & operator. I did sell the EQs to offset the cost. Couldn't swing the new cam, harland sharp rockers & the head. Tax time is here so time for a cam upgrade. Anyone have a recommendation?

So I finally got my trickflow 190 powerport heads installed & got the car on the dyno. My previous heads were a set of EQ magnum heads that were done up by IMM. Very disappointing results, car only gained 2 rwhp and 6 rwtq. Guess the EQ heads were the real deal, should have left well enough alone. Car made 292 rwhp and 311 rwtq @ 5500rpm 36 degree total timing & AFR 12.85.

OP--I sympathize. After reading this entire thread, I would have told you to save your $$$$. EQ's professionally done are a bad *** head and you are not going to pick up 100 hp or even 50hp or even 25hp going to TF's. In fact I've seen this scenario playout many times in other forms and I think you are FORTUNATE to see ANY gain. Don't get me wrong as some reading this certainly will---Had you been starting with a inferior head to begin with I would definately be on board with the TF's.

Statement of fact: I have not as of yet worked with the TF's. I love their chamber design from what I have seen on the internet. I love the flow curve that TF claims. That being said I do not know why their is such a strong following and blind faith in a largely untested product. I have worked extensively with the EQ's--They are hard NOT to make great power with. Eq's are no longer being produced so I will save my breath. J.Rob

p.s. If anyone else is thinking of selling their EQ's and moving to TF's--shoot me a P.M. J.Rob

How do you not know in what regard I say this, Unless you 'cherry pick' my quote.
Quote the rest of my post and you'll have a better understanding of what I'm saying, not that I dont think you already do...
Big heads need bigger builds under them plain and simple. For his combo and cid/compression...the smaller iron head wins with velocity ,given that the numbers should be close through .300-.400 lift...its also got more heat. I'm still wanting to raise the comp up half a point when I switch to aluminum.

My buddy bought a set and wanted to bring them over for some flow testing but I’m a little to busy right now and he’s not going to use them for awhile so no big hurry. Michael Beard also put a set on his 10 second car and he puts on lots of runs so I will follow his progress. Problem there is he is also switching from a 727 to a powerglide.

I dont know if you need to bump compression.
If you have stock 71 pistons and closed chamber heads you should be good.
A good cam grind will solve everything.
Call a guru and ask. But know all your specsbefore calling.

What people mostly do,make multiple changes at once...but miss out on which was the most impactful.

36 total mechanical adv seems like a lot for that combo.
I may be wrong. ?

I have TFs on my 340
It likes 30 to 32 degrees total timing
I have tested it up to 36*, it fell off on power
Called Trick Flow and they said max 30 to 32 degrees.
I run 91 pump gas with 10.4 comp.
No detonation even at 36* it didn't ping.
But noticeable loss in power from 32*
Just my experience..
 
WOAH
Do you like the power curve of the 268 Voodoo Range: 1800-6200; or do you want to go to the more converter lower gear route because that's where most of the suggestions for more lift than the .525 are leading you
You might talk with B3 racing to see if your geometry needs changing but most likely with the TF's you are ok if you got the right pushrods
but that's what I'd check first
check the sweep of the roller on the valve tip with some dykem or a magic marker and report back

another option since you have the roller tip rockers is to go to a solid cam
you can keep your low end and get some more top end
headers?
the Mr gasket head gaskets would help
what year 340
and what's your cranking compression
get the numbers and ask AJFORMS to run the numbers for you
then think about pistons or a cam change
now chill and get to work
at what rpm do you need more power?
 
When I hear "it only made X more horsepower and Y more torque", I instantly think you don't know what you're talking about (I ain't saying that's true, that is just the first conclusion that I jump to).

Heads can make an 50 HP clear across the curve, except that ONE spot where the original heads peaked, and your statement would be true, yet untrue.
The question is: How much power over the previous setup did it make, and where? Got any way to post your before and after dyno curves?

I don't question these guys that say this or that cam is needed to optimize what these heads have to offer. They know more than me. But I know enough to know you can't describe two cams with two single numbers.

And when did EQ heads get disco'd? I have only been looking at aluminum (where do the Ed Heads fit in this mess?) so i haven't looked at EQ's, but I thought about buying a set since I own 5 magnum engines, but they show still available?
 
The EQ are good heads and even better ported
I am not surprised he did not get a big gain with OOB TF's
but think of the weight he saved :)

No never got flow numbers from Brian on the heads. The car ran great, definitely regretting my 2400 head investment. Just figured the trickflow would be a better head. I guess the cam might be hurting performance but I figured I would have at least picked up 15 or 20rwhp with the trickflows. Looking at the dyno graphs from both setups, the power curve & pulls look almost identical.

Dumb question.
Why would you have spent well over 2,000 dollars to pick up even 15 or 20 horse? Even if what you had hoped to happen did.... extremely poor gain for dollars spent
You have nowhere near enough cam/ motor to see much improvement as currently configured.
I probably would have asked Brian or any number of others before throwing that kind of money at what you have going on.
Sorry, i know hindsight is 20/20

Pretty sure the OP didnt make the purchase thinking 20hp was all he would get.

I also believe with the right cam and tune he can see a substantial gain over his EQs .

I think we have all made a purchase like this at one time or another.
