AFR and Trickflows: Dyno graphs & street fun.. lets compare shall we?

[Methodical]

...Keep in mind, that there are custom camshaft differences depending on the goal asked. One FTI cam is not the same as another FTI cam That can create the variances.

Took the words out of my mouth. I was thinking the same thing. There will be differences (small or large ) who knows because no one is providing the custom cam numbers. But there will be differences. Are the custom cam folks required to sign a nondisclosure form?

When I've read about these heads, they do state that they're are CNC'd, but I'm not 100% sure if all of their models are.

Directly from Jay's site, " CNC profiled combustion chamber standard", but others are Full CNC'd directly from Canfield.

One of the cool things about them is that they come with springs to match the cam, I'm not sure if AFR/TFS does that. Do they? (honest question)

Seems like I have read recently somewhere that AFR is now supplying
better springs on their heads these days

Of course ... these cams from Ed can be different but from comparing the various
combos ... the results you see on the dyno curves don't always seem to be all that
different.

No ... I did not sign any kind of form but I was asked not to disclose the cam
specs.

Here are three TFS head combos from the main group above

Notice all three run the longest runner intakes

Grady do you just collect dyno sheets or have a dyno at home?

The AFR heads are FULL CNC from the combustion chamber to the ports on both sides.

The AFR heads now have .600" lift springs on them, minimum with 8mm valve stems (aka: lightweight). I believe the Canfield heads use the heavier 11/32" ones, but I am not for sure.

Canfield, according to their website do not sell all of their heads full CNC'd.

Not speaking about cam specs is just understood. No need to sign any kind of Top Secret documents

Collect ... Scarf up ... Steal

Call it what you will

I gather data that I find to be more reliable than .........

My cousins best friends brother in law who knows a guy said ........

"If you wanna go really fast in your Stang" .......

"You need to" ... yada yada yada

Hummmm ... a dyno at my house

That would be fun

Well ... It was you who started all this madness

Have you seen anything here that has surprised you

I find great flow numbers in AFR but also find that TFS out of the box flows well enough to build on. And I dont know if its a flawed design.

All of the graphs, dyno info, and opinions posted here are good confirmation for me. Both are capable combos, with the edge going to the afr's. guess it is true to some respect, you get what you pay for It was also interesting to see some of the numbers stroker combos are making with the 165s and tfs's, something to digest for the future perhaps.. if that horsepower bug resurfaces sometime down the road

also, you brought up stud vs ped rockers.. Ive looked into that too and I agree that stud is the way to go. I also like the "big stuff first" mentality.. where you build your h/c/i first, then install the bolt ons later when the moneys there. Overall, good info
