Trick Flow heads, etc.

Where do you get the distorted impression that a motorist can drive a car without a license and registration? Every state in the union requires license plates on vehicles that are driven on public roads and the people that drive them are required to carry a license to operate them when they are driving.
I'm not some goody-goody law abiding guy and I'm certainly not against modifying my cars.
I do know that according to Federal law, you are not allowed to remove emission control devices anywhere. Now, the fact that most states do not enforce that law renders the argument somewhat moot but if they wanted to enforce it, they could.
There are several states that joined in with the CA lunacy in regards to phasing out of new gasoline and diesel car sales in favor of EVs so it is absolutely possible that some states have similar emission control laws.
My question was a simple one and you made a mountain out a molehill.

You can remove emission equipment from a pre 1980 vehicle in Missouri, to be sure I just looked this up. Where I live in Missouri we don't have any emission inspection

I have used Trick Flow heads in 2 builds with no problem. I have another set to use on another project. I had B3 do the rocker arm geometry correction.

I've been told

Let me make it a little more clear for you. In a 340 cubic inch motor the amount of flow needed can easily be supplied by a Edelbrock / speedmaster head. Like I said and I'll stand by it unless you are really turning it up and have the cam lift available to take advantage of the trick flow head gains will be small it's been proven time and time again. But if you're talking out of the box yes trick flows have a higher power capability everybody knows that so thanks Captain obvious.

What camshaft configuration would you suggest?

Yes given my choice I would still go with the trick flow heads if price was not an issue that being said you're looking at $2,000 difference in price if you include rocker arms. To me that's not chump change but if 450 hp or over is your goal trick flows would be a better option unless you already have Edelbrock style heads then porting might be a good route.

After researching it, I'm leaning towards a 416ci stroker kit now.

TF flow more everywhere not just above .550"



Using same SM valve.

Here the SM been ported, TF OOTB.

Is that on the same bench?

In point of fact the TF head IS ported.

What exactly was done to the SM heads by way of porting?

Yes Sir, There all from Earlie A's testing.

 

[Icetech]

And that's a good thing!

So.. if you don't like it other people shouldn't be allowed it then? FREEDOM!!! not the place for this discussion though back to silly head talk.

 

[Earlie A]

I will be away from my computer/data for a few days, but 273 is correct that the TF is quite a bit stronger flowing on the bench throughout the flow range. As a matter of fact, one of the things I like about the TF is the strong mid lift flow. One of the things I want to learn with dyno testing is how the strong mid lift flow affects power output.

Compared to a ported SM?

 

[Earlie A]

Compared to a ported SM?

I was referring to a stock 2.02 Edelbrock/SM/Promaxx vs a stock TF. There is no comparison, the TF flows more. But as you mentioned, the TF is ported. Comparing a ported 2.02 SM/Eddy to a stock TF is a different story. The TF still wins on the bench, but on the dyno or track, ??????

Same with a 2.08 ported head. The TF again probably wins on the bench………..

 

[AJ/FormS]

Did anybody notice , that this stock-stroke 340 is going into a Dakota at perhaps 3600, plus driver, pounds, with a 272/278 cam and 3.92s with tires likely around 29 inches tall?
This could be pushing 12 pounds per cubic inch, and she is geared 30= 3500 in first gear, 2100 in Second. Where are you gunna stall that?
I sense major performance disappointment here, until the engine gets up on the cam, which in Second gear might begin around 65mph=4700rpm.

One of the TF designers said for there street heads they mainly focus on .300-.500" numbers cause that's where most street cams live.

From what builds I've seen out there with dyno results, Edelbrocks seem to make around 475 hp in basic 408 trim (10:1 airgap headers 240 cam etc.) and 525 ish hp with TF.

 

[Dart Frog]

I look at those numbers and I see confirmation to my point. But to each their own.

Exactly

I don't see how you get that.

 

[Newbomb Turk]

And that’s what limits power.

You have to have flow AND lift.

 

[Dart Frog]

If you're going to a 4 inch stroke by all means jump right to trick flow 190s if you can afford it.

 

[Newbomb Turk]

I don't see how you get that.

I think he’s saying at those lifts the TF isn’t the dong beater everyone wants them to be.

I'm switching gears. Going to a 416 stroker with an A-518 transmission, I'll leave the heads and camshaft decision to my engine builder. I can always go to a Ford 9" should I need to make a gear adjustment. Thank you for the input!

May go to AFR's. I'm meeting the builder tomorrow to drop the block off and discuss.

 

[273]

From the few builds out there with dyno results the ootb TF seem to make 50 ish hp more than a similar built ootb Edelbrock headed engines.

 

[273]

Is that on the same bench?

Far as I know you would have to ask Earlie A, I imagine he does all his work on one bench.

In point of fact the TF head IS ported.

I get that, never said they weren't, so far people have been talking ootb choices, so I gave info on those choices that may help the OP.

What exactly was done to the SM heads by way of porting?

Far as I know, said wasn't a professional port job.

 

[fishmens67]

In a 340 cubic inch motor the amount of flow needed can easily be supplied by a Edelbrock / speedmaster head

The Trick Flow head will outperform the Edelbrock/ Speedmaster heads throughout the lift and RPM range. A far superior head, not even close.

 

[fishmens67]

Yes, but OOTB, ready to run, 281cfm @.500 and 295 cfm @.600. I think we can make some power with them on 340ci.

 

[Mean416]

The TF head is a somewhat modern head design. It's a better head, and will make more power everywhere than the eddy, ootb. Regardless of displacement.
