Trick Flow 240...

The “240” is the intake runner volume in CC’s.
It’s not what the head flows in CFM.

All that sounds great, but how much better than stock can a fully bolt-on cylinder head be, and exactly which segment of the big-block Chrysler market are Trick Flow’s new PowerPort 240 aluminum castings intended for? The company’s in-house test engine mule speaks volumes. “Our new big-block Chrysler heads flow 334 cfm on the intake side, and 262 cfm on the exhaust side. For testing purposes, we built a .030-over 440 with 10.5:1 compression and a 241/246-at-.050 camshaft,” Mike Downs of Trick Flow explains. “On the dyno, this combo made 620 horsepower on pump gas. We feel it represents the type of combination many Mopar guys build, and obviously there’s the potential for these heads to support even more power by running more cubic inches and a bigger cam.”

The HR article is a mess, the cam specs are different than the TF specs. Andy F built a 470 that knocked out 700 HP with the TF240 heads, that is well documented on HR Mag.
 
I ended up making a peak of 750 hp with the 240 heads but that was a pretty serious engine with a large solid roller, fully ported intake and a take no prisoners oiling system. My street engines usually make around 600 hp with the 240 heads. Pump gas compression, mild hyd roller, port matched intake, etc. The Trick Flow build up is a reasonable street engine build but those heads are capable of a lot more power if you're willing to turn up the wick. On a drag only car a guy should be able to achieve 700+ hp with 240 heads if he is willing to spend some money on good parts.

That is a ultra broad & general question so the answer is the same.

An easy 100 hp to 250hp and more.

Reason? Build dependent as well as head dependent even though the answer is focused on the TF head.

High performance street and low to mid level track performance.

Why? Same reason as above.

It is not a racing head. But that doesn’t mean you can’t race it. (Certain) MoPars Stage VI S/S - racing head would port out to about the TF level. But that was yesteryear, it’s now this year and things change.

O.k Andy, I thought the 750 was with the 270 heads. I should have verified it.

Even I get confused since I did a lot of testing. I had two 470 inch engines that I was using and I was constantly swapping parts. We ran about 150 dyno pulls over a two year period so it can be tough to keep it all straight. I think the very best runs for the 240 heads were on the 470 dry sump engine with the ported Wilson intake and a Dominator carb. Those very best runs got into the 750 range but I'm not sure I ever published any of that information. The 270 heads picked up another 30+ hp on that same short block.

My short summary is that the average guy should be able to build a 600 hp engine with the 240 heads. Pump gas 470 or 505 with a modest sized cam and a good single plane intake should be 600+ without any special parts or work. The heads can be pushed past 700 hp if you work with a good engine builder. You'll need to port the intake and pick an aggressive cam and dial in the carb and stuff like that. This is all with out of the box porting. I never touched the heads other than verify guide clearance. We did change springs depending on the cam and rocker arms but that was it. They are great heads, best ones on the market for the average guy to use.
 
And again, FABO has the answers for anybody willing to do the homework. I have been thinking about the TF240 for awhile and this just made up my mind. Thanks AndyF for the info.

LMAO! Yea man, here here.
Also a big shout out thanks to @AndyF
These will be my big block heads. Like he said above, “best ones on the market for the average guy to use.” Well, average guy here!
LOL
 
The engine I just finished up for my Coronet is a more typical 240 engine. This is a 496 (426W with 4.25 crank) with 240 heads, a 239/245 hyd roller, 10:1 compression, TF intake and a Holley Sniper. This engine made 610 hp and 630 torque on the engine dyno. I'm in the process of getting it ready to go into my car. Should have it hitting the streets this summer. Very simple build with six pack oil pan, timing chain, standard off the shelf rings, normal bearings, normal clearances, etc. ARP main studs is about the only upgrade from a stock type rebuild.

Nice! Did it make that power with the Try-y headers? That's my next big decision. I am pretty much set on the TTI 1-7/8 header but only because of what I read about the Schumacher's killing big power. Now if you made that kind of power with them I may reconsider.
 
No, those tri-y headers don't fit on the dyno so we didn't run them. I'm sure they kill some power but I'm not worried about it. I used to run cast iron headers in the car so the tri-y headers are actually a step up. The car made tons of power with the cast iron manifolds so I'm not concerned with how much it will make with the tri-y headers. It is a street car, not a race car. Here is the setup I used to run. This combo made 480 rwhp on the chassis dyno and the car was fast enough to get into serious trouble on the street. I don't need more power.

I got 613 hp and 625tq using TF240 heads and a solid cam on a 451. 10.75 comp with hooker headers that needed 1 pipe slightly bent. It made 13" vacuum and was extremely easy to drive. I would recommend what Andy did a 470 would be even better. The motor revs quickly as well. The best thing is to get a light piston like a ross like I did and good rods. Good luck

Would you mind sharing cam info ?

It's a Cam that my Buddy Tom @ TK race in Montreal specked out its a 236-240 590-600 on a 112 LSA Hydraulic F/T. Also he cleaned up the port on the intake side because on 2 sets of 240's there was so much turbulence it was bad. Removed the ribs from the CNC and that cured that up very nicely. (Heck when was the last time you saw ported heads with Ribs i\on them LOL)
For what it's worth we got 318 max on the 240's out of box, Every flow bench will give different results.

The same horsepower Andy made with his 470 is possible with a 451. The 240 Trick Flow heads can be touched up to flow with our Edelbrock RPM heads and they have made 780+ HP on a pump gas 451.

And yes, we have run the TTI headers on the 240 Trick Flow heads.

Do you have some pics of where and how much I would need to touch these 240 up ??

Do you do this for a living Sir ?? If so I apologize. I don't know you. Usually everyone on this site is eager to help one another. I totally understand if this is your living. In that case what does it cost to have you do these brand new 240 heads that I have ?

I’ll suggest some reading starting with the threads he started. Go under his user name and search his posts. At the bottom, there is a button to see all posts started by IQ52. Read up.

If your interested in history, his pops was chin deep into race cars way back. Jim is retired. You can find his family name in the record books for decades. As well as publications like Hot Rod.

Wow that cool. I will assure you I will do that. Thank you for the info. I'm a study guy anyway.

Gadzooks, no need to feel like a jerk, you said nothing offensive! No hurt feelings here. I just don't have any pictures of worked 240's. I have stock ones on the shelf. My son, the cylinder head porter, is building other types of heads now.

He makes the skulls from exhaust tubing and mounts natural antlers on them. Sometimes he will make antlers from the exhaust tubing if one antler is missing, as seen here. Then I make a neck or desk mount.

It is much less pressure than building engines or porting cylinder heads.

Andy,
I love your articles. I bought your book before starting my 512 build. Great book by the way! Check out my build for the 512 in my Barracuda in my garage.
Thanks,

Glen

Andy , have you got an opinion on the diff. between a victor 440 and a trickflow intake? I have polished victor that I cleaned up and flowed at a friends shop. We got it to flow as good as my raised port heads, (350ish) with really close runner scatter ,but really dont like the very small plenum it has .----505'' . ????????

Best intake you can get these days (without spending a ton of money) would be a Trick Flow intake from Hughes with their deep port match. If you want even more power then send the deep ported intake from Hughes to Wilson Manifolds and they'll take it over the top.

My 470 made close to 720 hp with the 240 heads. That is a pump gas engine. Here is the article from Hot Rod: We Test Intake Manifolds and Carburetors on our 400 Stroker in Search of Ultimate Power - Hot Rod Network

I'm in the process of dropping this 470 into a Duster. The Duster is a bit of a project car so it will be a while before I'm on the road with it.

Hi Andy, looking at the pics in this article, what valley plate is that? It looks like it covers the valley only and you can change intake manifold without disturbing the valley cover. I’m in Australia, where could I get one from? Thanks in advance
