Is there a specific aftermarket rocker arm they work best with geometry wise?

You know I read the TF article in hot rod magazine about these heads. TF said they wanted to make a head so that we can run the factory valve train BUT now your saying you recommend that we would need to use roller rockers with these heads. So which is it? Am I going to spend another $700 on Roller Rockers just to run these heads?

According to the summit webpage estimated shipping date is one month+ (10/19) if ordered today. A little more than the announced 10 days. Any further delays to be expected?

Since it didn't say nothing about Rocker Arms until the very last I assumed it they recommended rollers period. Andy the cam I was going to use was a 232-238 grind and 514/532 hydraulic I think. I was still wanting it to be very streetable and make long trips but would like the extra hp these heads bring also and run a dual plane intake also. I really wasn't wanting to buy the roller now but if I had to I would break down and buy them. What are sidewinders?

Any chance of building a small block head

Any standard rocker arm will work, but Harland Sharp makes a short and a long. Our head will require their short rocker arm.

How does somebody tell the difference between the "long" and "short" Harland Sharp rockers? I don't see anything on their web site that says this.

X1.. I have mine HS rockers 1.5 since -91. Used them on 906 and Eddy RPMs do I have short or long arms

I think what he is referring to is the 1.5 ratio and 1.6 ratio...

IIRC, Todd from Competition Wedge (NY) worked w/ Harland Sharp to come up w/ a shorter version to address this, but don't know what the end result was as far as HS offering them for any particular heads.

Free research for you prospective (or committed) Trick Flow head purchasers:

Trick Flow PowerPort 240 1.560 Spring

Valve Springs, Option 2: 1.560" o.d. dual spring with damper
240 lbs. @ 2.000" installed height
600 lbs. @ 1.280" open
500 lbs. per inch rate
.700" max. valve lift

TFS-16318-16 Spring
Inside Diameter of Outer Spring (in): 1.136"
Inside Diameter of Inner Spring (in): 0.750"

Trick Flow Ti Retainers (the only TF P/N I found that would match the TFS-16318 spring):

-------------------- OD ----1st Step - 2nd Step - Retainer
TFS-214T0525 --- 1.500 -- 1.110 -- 0.710 ---- 10* (+.050")

My experience w/ running Ti retainers on the street w/ springs having steel dampers hasn't been great, in that the dampers will definitely cut into the Ti retainer, yet a chro-moly steel retainer isn't fazed by this. So, I did some research on retainer options, specifically tool steel, for those who may want to swap out the Ti retainers for just that reason.

I don't know if the retainers w/ the 1.140" step OD for the outer spring will actually fit the TF-supplied spring since its ID is listed as 1.136". Not sure if those could be installed as a press-fit, or if that's simply too large to work w/o reducing the retainer step OD. IMO, the tighter fit, the better. However, it also looks like some of the other tool steel retainers I've listed should still have a better fit to the spring than the Ti retainers I believe Trick Flow is using w/ their supplied springs.

FWIW, if I was buying some TFs for my application (.650"-ish solid roller for street/strip), I'd probabaly get some Manley 23647TS tool-steel 10* retainers and expect that the installed height may need to be corrected w/ the change in retainer brand.

"You results may vary!"

Here's an image album of them: Powerport 240 gallery

I think there will be a lot more information available soon from various sources, as the first pair will arrive here at our shop Tuesday.

I'm definitely buying a set of these heads. I wish they had a matching dual plane intake to match.

Lift Value Intake Flow CFM Exhaust Flow CFM
.100″ 78 58
.200″ 154 130
.300″ 230 186
.400″ 282 222
.500″ 310 243
.600″ 326 253
.700″ 334 262
Tests conducted at 28″ of water (pressure). Bore size: 4.350″; exhaust with 2″ pipe.

Brad, which head do you feel would be a better option to bolt an RPM intake onto for $1979?

A customer of mine supposedly ordered a set a week ago, so I'm hoping to have them here to test fairly soon.

I should have a 470 inch B block on the dyno in a month or so with the TF heads. Pump gas engine with a solid roller. PipeMax says it will make 680 hp so I guess we'll see how close it comes.

680 was the low, 700 was the high. This was based on a total intake flow of 310 cfm which is a bit of a guess. Once I have the heads I can bolt the intake and the carb on and see what my little flow bench says.

Andy, keep us posted on your results, these heads are probably going to be one of my first purchases after I get back in the states and the molnar crank and rods shortly there after, I am starting to get excited about this 511 B engine build.

I'm definitely buying a set of these heads. I wish they had a matching dual quad tunnel ram intake to match.

FINALLY ---- coming to your senses


Now about that Gentry guy

Fixed it for you... B and RB, with room for max wedge porting too, please. [edit] forgot cast in injector/n2o bungs[/edit]

I think there will be a lot more information available soon from various sources, as the first pair will arrive here at our shop Tuesday.

Hahaha....... Kinda hard to argue with you guys these days, you can't buy a block for a small block. Wish I liked Chevvies.....

B3RE relocation kit to be able to use 1.6?

Shannon's Engineering in Storden, MN gave me a killer deal on new HS rockers, beating retail by 4200 or so.

http://shanonsengineering.com/pages/about-us

IM stoked, but Im also curious as to why its taken so long for trick flow to come to the table for the Mopar Masses, And still no options for the small block stuff.

I just don't understand why most aftermarket companies cater to the ferd, and chivy crowds. I know in my small town there are a lot of small block mopars running around.

3. Most Mopar guys are CHEAP SOBs

I can't stand it when people say this, we Mopar guys spend more than the Chevy clowns do!
So how are we cheap?

1. Death
2. Taxes
3. Most Mopar guys are CHEAP SOBs

Yeah, I'd say you can pretty much count on those three things in life.

I have numbers from my bench and your stage 6's, so it will be interesting to see how they compare side by side. IMO, what those 6's really had going for them was decent flow from pretty small port volume, which I feel is a good combo for moderate cube pump gas motors running in heavy-ish cars with closed exhaust systems.

OK, so I do want to add that this was my comical way of responding to 64Post's comment. But (as Monte & Al pointed out), there's still a legion of Mopar people who aren't that far removed from the ported '906' heads, .590 MP cam , SS springs world.

I'm extremely happy that Trick Flow came up w/ their new heads and hope they're profitable enough for the company to venture even deeper into the Mopar arena.

Summit lists them now. just under $1,000 with standard retainers and $1,099.50 with the Ti retainers.

http://www.summitracing.com/search/brand...par-big-block-b

I thought these were 75cc ??? Summit says 78 ?

I know someone that wants to put a set on a 500" engine , but the chamber size turns makes his combo over 11.0 , he wants a 94 oct or less street motor.

I should add, clarify.....my comments above are generic in term and not specific to the Trick Flow pieces. Actually TF has it right on these if they are at 1k ea assembled. Proof positive this can be done and done right.

Jerry, you are missing the point. Yes, this is a nice head at a good price. But the problem is the market it is aimed at. This is just one of a BUNCH of heads pointed at the warmed over stock motor crowd. THIS is the area where most Mopar guys spend money.....NOT real racey stuff. The last GOOD inline valve race head was the B-1........and how long ago was that? And at this point the Predator head is several years old. As old as those heads are, you see few B-1 motors and fewer Predators. So why is somebody going to sink a ton of money developing a NEW "race" head, when not many even bought the older ones that are still available. The "serious hp" Mopar racer is just a VERY small market

does these heads has max wedge ports

I understand that.........but there has to be a REASON that no company CHOOSES to do it. What do you think is the reason they don't?
- thats the million dollar question, I think its fairly clear why those who have been or is still currently marketing the high end stuff didn't prevail. -

As far as the "frivolous" comment. So is it your opinion that someone who wants to build enough power to go faster than 9s in an average weight car is frivolous - No. Paying far more than fair market value -

does these heads has max wedge ports

My understanding from the guy I spoke to at the summit nationals that a max wedge port is the next step and about a year or less out for production.

That head at 2800 pounds has 8 second NA pass capabilities.

This is no doubt a entertaining conversation! If the heads are as advertised, anyone that doesn't think they are different from what is already offered is BLIND! Trick Flow knows it or they would not have made them. They know the market is there, and there right. I'm a mopar guy, always have been and always will be. I don't need a 1,000 Hp engine, I'm a bracket racer. Duster weighs 2400 lbs and has ran 10.0x with stock 452's, shifting @ 5,600. The engine blew and honestly if it weren't for trick flows new head I'd rebuild the 452's. No one else offers enough bang for the buck. The mopar parts on my car are more expensive than chevy parts, I knew it and paid any way. I'd do it again, I still believe it was cheaper in the long run.
Would I like to have a low 9 or 8 sec. motor, you bet. But not if I have to pay 50% more.
I'm looking forward to the potential these heads should offer!
