Hey all, just looking for some feed back, or opinions as to how the new TF intake would perform on a "replacement "
style aluminum headed 440 ? Something with a 210cc runner , i.e. Stealths,Eddie's, or Promaxx's like I have on my car..I have the .528 purpleshaft and a Performer RPM intake on the 440 now and I really like it.
I was just contemplating upgrading to the TF intake and possibly the .557 purple shaft, since that intake and cam both come on at 3k rpm.
On paper, it looks like that combo would play real well with my 9.5" 3600 converter and 3.91 gears on 28" tires. My cr is 10.3-1. Any real world feed back on the TF intake is much appreciated. The runner length looks like it would still make great torque reasonably low.

To be honest, the only way to know is to try it & compare track times.

Absolutely, ..I was just hoping someone already had the track time or Dyno info and was willing to pass it along.

The Trick Flow intake is a very good single plane intake. It will most likely kill off some low end torque on your combo and pick up a little bit on the top end over the Performer RPM. I wouldn't recommend that swap for a daily driver but it might pay off for a bracket car.

Thanks for your input Andy, much appreciated. It was because of your research that I chose the .528 cam I'm running now. Do you feel the TF intake would be a poor match for the .528 cam? I keep telling myself to keep this build conservative, but the more it progresses I keep leaning toward a more bracket race approach. It's just a weekend
thrasher that I take to the track 2-3 times per year.. it needs body work and interior, but going faster always seems to take priority. Lol.

Drive it for a while with the RPM Performer and then switch to the Trick Flow and see what you think. On the street I think you'll notice that the engine feels softer when leaving a stop light. It might feel stronger at the top of each gear but typically you never pull it to redline on the street anyway since you'll be making so much noise and going so fast that if you're in town you'll get busted pretty quickly. If you live out in the country and have lots of straight roads to race on then maybe you'll like the TF intake better. Hard to say without trying them both.

I have been running it with the RPM for about 5 years now, it has always ran well with that intake. I have since upgraded my heads, converter and exhaust. .. I'm just kicking the idea around of trying a single plane. The TF looks like about the best available today as far as an "as cast" piece goes. I was just curious if anyone has A/B tested the RPM vs the TF. Sounds like I'm just gonna have to pull the trigger on the TF and see what it does. Thanks for the input Andy.

I've run both the RPM and the Trick Flow intake on my car.

Have you tried an open spacer with the Performer RPM to see if it responds to a larger plenum? The Trick Flow doesn't sound like a good match for the combination described.

Yes, I run it with a 1" open phenolic spacer.. it seems to like it. My initial purpose for the spacer was to keep heat off the carb.
Part of the reason I'm considering the TF intake is because my combo is not very far off from the combo featured in their ads.
My compression, my c.i.d. , my cam duration, my carb and exhaust are all very similar to the combo they
cited in their ads. You know, the combo that produced 620 hp. !! however inflated those numbers may be, the only big differences between my combo and theirs are the heads, the TF 240's vs my 210 cc aluminum heads[I know, this one is a biggie]
and the big single plane intake vs. my performer RPM. I really like the looks of the TF intake and I think my e.t. would benefit from a little extra top end charge.

what does you car run right now? did it pick up going from (i'm assuming from your signature) the 906 heads to the promaxx heads?
did you port match and open up the pushrod pinch in the promaxx heads?

It sounds like you're looking for someone to say: "Yeah, that's a great choice of intake for your car!" I'm not that person.

However, if you have the $ to buy & try one, please post the track results. God knows I've certainly spent $ on things other people told me weren't the best for the combination I was running.

That is a good question.. lol.. I haven't been to the track yet since the head swap. Waiting for it to cool down a bit out here in So Cal. Probably early Nov I'll be hitting the track. As for opening up the pushrod pinch, I didn't, because the pushrod pinch on the Promaxx's vs the 906's was huge !! I could fit the box end of a 3/4" wrench trough the Promaxx's pinch area.. I could barely get the 3/4 into the port on the 906's. And, Brad is right... I'm kinda fishing for someone to tell me to go with the single planene.. lol !!

Over all, the purpose of this post is, I was curious if anyone has tried and tested this swap on a combo similar to mine.

Someone has to be first....... looks like it might be you.

^ yeah...

isn't an intake swap on a big block pretty easy? do the swap on the same day at the track and find out what you pick up or lose...

[spoiler][/spoiler]

Intake swap on a 440 is super easy.. just the carb and 8 bolts. I'll probably need to jet up from the dual plane.. ?
Sounds like a good idea.

I just gotta cough up the $350 for the TF intake. Pretty sure I won't find one used.

You're just late to the party. I did back to back testing last year and then sold my slightly used Trick Flow intake to a Moparts member.

Story of my life Andy.. lol.. what intake did you test it aginst?

Perhaps a different spacer to try? http://highvelocityheads.com/st4150...-sweeper-on-dual-plane-intake-manifolds/

Wow, those look pretty crazy.. have you ever tried one Brad? My only issue is, I want to stay with something that will insulate the carb against heat
Better than aluminum.
