Any Trickflow Top End 440 Users Out There?

[Road Grabber]

I’m looking for any feedback reviews on the street ability and performance of this kit that Trickflow claims to provide dyno proven kits that push upwards 600hp when assembled in a 440 Mopar.

Is the cam/engine street worthy?
Can power brakes function with the cam?

Thanks

I built this one a decade ago…
Trick Flow 537 build

The 446 cubic inch version of it is currently sitting in my shop. I’m guessing it’ll make somewhere around 560hp.

Awesome job.

So that was a custom ground cam?
By who?

How did you come up with the cam specs?

I have a six pack engine with a builder with a very mild cam it seems. The numbers have come in low and I am investigating a different cam but don’t have a source for advice. Howard’s cam suggested my cam. I had issues with bent pushrods and awaiting more dyno tests. Builder believes the pushrods weren’t strong enough.

I’d like to contact someone who can give some solid advice with Mopar and Trickflow experience. Any suggestions?

I've built a bunch of Mopar big blocks with Trick Flow heads. 600 hp is easy, so is 700 hp. I pushed my pump gas 470 close to 800 hp with out of the box Trick Flow heads. Typically you aren't going to make 600 hp on a 440 short block with a street cam. 600 hp is easy with a really good intake manifold, correct headers and a race cam.
A street engine typically will have a dual plane intake, smaller headers and a modest camshaft. Combine those things with TF heads on a 440 short block and you'll get an engine that makes a little over 500/500. It will be a really nice engine. Should run nice and smooth, pull hard, scare the wife when you floor it, etc., but it isn't a race engine.

Can you suggest a cam(s) for a street BB you had experience that will allow power brakes and produce those high torque numbers?

I don’t need a full race engine but would like to get the potential using those heads.

Would you know if the cam sold with the Trickflow top kit is one of those cams?

Thanks for your input

Did you Ask TRIK FLO ??
They’re Tech Support is Very Good !

I would think the Trick Flow cam would work but if you wanted better low speed manners then drop the duration a little (say 5-6*)and maybe on a 110 instead of a 108 and you will have all you want/need.

Do you know what your manifold vacuum is?

I have heard of cam grinders making provisions for power brakes vacuum.

Can you give an example of what that would look like across the cam specs?

Thank you

I do intend to call them. Thanks

I can tell you they weren’t helpful when I asked about head gaskets and they never mentioned pushrods. They should advise 3/8 thick wall rods. It is not in their list of recommendations paperwork either. They listed Felpro 1009 at first and now they sell their MLS gaskets with the kits. I think because they had issues with feedback which was my experience….

The TF hyd roller cam makes 600 hp but it would be too much cam for "smooth" street 440. It would work okay for a 505 or 512. The TF cam is 243/247 so it is aggressive for idle quality with closed exhaust.

I use a 239/245 custom ground hyd roller in my 496. It has a lumpy idle but manifold vacuum is decent. However, it requires a lot of ignition advance at idle and the AFR needs to be tweaked just right. I use EFI with a digital ignition curve since that is the easiest way to dial the tune on a engine like that. My engine made 612 hp and 620 torque on the dyno. You most likely will not be able to duplicate those numbers with a 440 but you should be able to get into the 525/550 neighborhood.

You can watch this video if you like. It is a little boring but it is only a few minutes long. It shows a cold start of the engine in my Coronet. You can watch the digital dash and listen to the engine warm up. This is a 600 hp street engine with TF heads and a Holley Sniper. So if you watch the dash you can see what the AFR is when cold and how it leans out as the engine warms up. You can also watch the ignition curve and you can see the manifold vacuum. It is all there on the screen.

Basically it comes down to individual preferences and tolerance.

The TF cam makes great power when combined with their top end package, but I doubt it will provide enough vacuum for power brakes………and might even pose some low speed tuning challenges for the 6bbl(and imo, it would be a poor choice for ex manifolds).

I the other thread there was mention of previously running a MP484 cam?
If you were happy with that, driveability wise, you should be okay with something with 5-8deg more duration than the current cam.
If the intent is to attempt to run it with ex manifolds, I’d suggest 235-236deg max intake duration, and an lsa of 112.
For headers you could add a couple of degrees, and and tighten the lsa to 110.

Thanks for the reply. How does this cam fit into your vision which is installed as of now?

By “adding duration” would that be adding duration to both exhaust and intake? Forgive the lack of cam experience with numbers. I’m not a track guy with higher than usual levels of exposure.

I placed it twice in case hard to read.

If running headers this would be good spec wise in my opinion. Listen to @PRHeads or have him grind you a cam based on whether you end up with manifolds or headers.

It easy to get consumed with HP and all the cam specs. I would put all that aside until you get the pushrods in and some Dyno work as well. You may decide you are happy with what you have(and I think you might be with headers). If you still want to run manifolds have Dwayne ( @PRHeads ) spec a cam for you and order it.

Take a deep breath and get some numbers first and then consider whether it is worth it to change or not.

Good advice. Thanks
Yes it is easy to get consumed and thanks for the contact.

Just trying to make some sense without having the same background.
Are these specs you mentioned @.050 lift?
Any reason why valve lift is not there when cam specs are mentioned?

Is lift not as much a factor?

Thanks for chiming in.

We have TF240 heads on a 440, and the Trick Flow Cam on a different 440. Both are 91 octane 11+ SCR street and strip combos. The TF cam even with 11+ compression is not a good fit for vacuum brakes with a 440, a stroker combo is closer to having enough vacuum. But you also could definetly pick a better cam than the TF cam in a 440 or a stroker and have even better vacuum.

You could piece together a lot better package than that kit and probably have less money in it. The standard Morel lifters are what the kit comes with, and they are not up to spinning a 440 to 6000 RPM with the spring package TF240s come with. On their dyno chart I think you can even see the lifters making the engine nose over early on the dyno before 6000 RPM. I am guessing that is coming from the HR lifters not being able to carry the valve terrain load.

We have that TF cam and 1.6 rockers on a 440 with E street heads. But have solid rollers lifters tight lashed cold instead of HRs. Its max power is at about the same RPM and we shift at 6800. Put a fork in that TF top end kit at 6200, it looks like it is done. Our lowly E street engine comes on hard where the TF240 dyno sheet dipped. Makes me wonder what they left on the table with those lifters.
