I'm sorry if I missed it but a short production run of a cut and welded LS based head after the Sr is done is still being planned, right?

Does anyone have any real world reliability info (preferably Bonneville or something else where you're wide open for minutes at a time) on sectioned and welded style heads?

Until it doesn't.


Paul has warned me about the higher CR of the Jr vs a carb'd head. IIRC, he said it should produce something around 10:1 CR. I'm fairly confident that the build won't depend on WI to prevent detonation. It's neither "full race" or tractor pull oriented - just a strong "3/4 race" kind of build - not "pushing the envelope". It will be running premium fuel, as always. The WI is just one of those "why not?" add-ons - beneficial for pretty much any application.

Thanks for the warning, FF. If the thing blows up, the "how not to" specs of the build will be forth coming.

I'm very excited to see how a head that flows ~50% better than stock performs.

Correct.


I thought a casted aluminum ls style head was the end goal?

I've read through this thread several times to try to decipher the intent/content. Initially I was also under the impression that these were all going to be aluminum castings. Somewhere in the many pages I believe it is clarified (?) that only the final (?) cross-flow version will be aluminum (?)

There are many "nuggets" scattered throughout the 10+ pages. It's frustrating to go back through & find and or resolve conflicting info.

The last two posts are a good example:

The JR and SR "U" heads are based on brand new Engine Quest bare castings.
https://www.techshopmag.com/enginequest ... der-heads/
The Crossflow Head is based on sectioned NEW LS3 heads made from 355-T6 aluminum alloy.

Neither Bruce or myself ever said anything about an aluminum "U" head or a one piece cast aluminum cross flow head.
There was some mention of the idea by others back in post #181 or starting with post #300.

The sun is rising :banana: as promised here is my 2-cents of clarification>>:

Two (2) U-Flow heads have ALWAYS been planned BOTH using Fresh New EngineQuest Branded aftermarket CAST IRON heads, manufactured off-shore and distributed to various EQ Dealers throughout the US . WE decided early on the make (2) fully ported versions one would be our JR head meaning "entry level" fully ported street-strip with max flow around 230CFM @ .600 valve lift.

The second U-Flow offering our SR head design, starts with the same EQ casting and differs from the JR head by using a larger intake valve, increased cross-sectional port area and is considered ALL that WE can achieve Flow-wise within the confines of the NEW EQ castings with a MAX flow of 265+ CFM @ .700 valve lift.

PROGRAM STATUS TO DATE>> Our JR head is complete in design, CURRENTLY in production, with (4) orders & deposits received, waiting final assembly and QC inspection then shipping one by one to our respective customers. The more difficult to produce SR head, primarily due to limited flow bench development time and compounded by the necessity of maintaining adequate wall port thickness.
WE HAVE NEVER CONSIDERED producing a new cast iron u-flow head of the heart shaped efi chamber design and or the pre-1987 non-swirl 240/300 carbureted chamber alternative.

As Paul Muller (Pmuller9) so articulately summarized above, the aluminum 3-piece welded cross flow is NOT a new ONE PIECE casting and probably never will be offered by us in that configuration. It would take an “act-of-congress” coupled with end-user DEMAND and an all-out NEW FUNDING effort to include that utopian alternative in our Big Six Development Program.
Keep the faith and pray for my continued dedication to this effort. Bruce

It's been done at Bonneville for decades with no problem. It all boils down to the integrity of the welding, but it's usually no issue. Plus, you don't need to run a 15 lb. radiator cap either to build that much pressure, just a 3-5 lb. is plenty.

When you say minutes at a time, how long does it take to go 3 miles @200 MPH? LOL

I was thinking more like pulling a long hill in 2nd or 3rd with a trailer.

That said, the more horsepower you have the less time you spend wide open. :lol:

Thanks 54-4x4 Comments from FordSix members like you motivate all of us toward our goals of excellence. Today was a good day at the shop as AL, along with the owner “Junior” of our 1ST Dyno engine, assembled the finishing components on the short block. Paul (pmuller9) will be posting several pics I took during various stages of the build. Can't wait for Long Block completion with head, valve train and followed by carburetion to ready engine for Dyno time. What’s taking so long is not waiting for parts but assembly is always with owner in attendance and assisting with the step by step process which is WHAT HE WANTS and we respectfully must honor his request. Stay Tuned there’s more to come as progress moves us toward Dynamometer start up. Bruce

I’m super excited to see the results of the dyno. I check this form every few hours looking for the results of this build and can’t wait to see them. I have not started my build yet but I imagine I will be throwing away all my build plans and copying this build once the specs and build sheet come out. Good luck guys and keep up the awesome work.

We certainly get an A+ for trying.

The compression ratio ended up being right at 10:1 with the 65cc chamber Jr head.

As most of you are aware OEM Ford and aftermerket equivalent from a number of suppliers such as Sealed power have a 22cc dish. The Dyno engine pictured here are Auto-Tec forged with a dish reduced to 18cc's. Gramps

We are starting off with the Crower 284HDP (19205) .509”/.517” 220/222 284/290 110deg and installing it straight up.
We want a representation of how the Jr head performs with the typical "off the shelf" cam profile and be able to compare to a stock head which would normally never get a larger custom cam.

1.72 ratio rocker.
The 3 Lunati Ford 300 six cams are the most detonation prone followed by the 3 Comp cams for the 300 six.

Hold on not so fast unless you are talking about> port velocity<. YOU GOT MOST of it, with the entire list of component attributes you mentioned above, ALL are very desirable and should work in harmony with each other to produce exceptional hp/torque. Let’s review the ONE you didn’t mention i.e. Port Flow !

NEVER forget the most misunderstood, almost unquantifiable, dynamics of Port FLOW.

Think of it this way>> flow benches in general (with exception of some OEM and a few aftermarket/race team custom-built “benches”) are indications of improvement in flow and NOT what your engine sees on the intake or exhaust side during a DYNAMIC running situation. Speeds in a high performance intake ports can easily exceed 250 mph. Those velocities are far beyond the capability of even the most sophisticated flow benches to replicate. I vividly recall when some of the more well-intentioned E&F Ford engineers I worked with , breathlessly brought in their new design cylinder heads to the Scientific Research Lab Super Flow facility for verification of excellence. Only to find out that there latest and greatest creation was a Bomb.

Thank you Gramps for expanding on my thoughts of some of the parts in your build.I was thinking the high performance head you have reworked would include what you know about the complicated world of port flow dynamics.It is nice to see your experience at work here.The anticipation of what's next is hard to wait for.

IMAGINE a Cross-Flow Aluminum Head that flows more than the 351 Cleveland Cast Iron (6-piece) furnace brazed Hi-Port Head, I cobbled up 45 years ago to Win my First NHRA Major the 1975 World Championship.
Here is RECENTLY released NHRA archival Video I and others have been looking for since 1980’s and could not find. Yes Great things are coming for those who wait.

1975 World Finals ITN Produced Video, Complete Coverage 47:33 min long.
Bruce Sizemore is driving his I/Gas Pinto vs Lee Shepard driving Reher- Morrison E/MP Corvette.
Action begins 32.66 minutes into Video for Modified Eliminator Final and WIN for Sizemore

TUNE in here on the Permanent Flow topic link for complete update on Junior & Senior head program. We will be discussing New order lead time, flow figures, chamber CC’s proposed options and restrictions. Shooting for Saturday post but could be SUNDAY. Either way you will have ALL the good stuff this weekend. Gramps :beer:

Awesome I will be looking for the update. I have been going into withdrawals with out any new material to read.

Permanent solution Program Update, goals and accomplishments.4/28/19
From the get go, our goal has always been 3-pronged e.g. offering 2 CFM levels of NEW U-flow cast iron EngineQuest aftermarket heads, intended to bolt on to the 240/300 Big Six; offering our customers significant performance gains in HP and Torque. The third prong has always been my personal challenge, to create a bolt-on Aluminum Cross Flow “USER-FRIENDLY” head that offers performance improvement levels vastly superior to ANY readily available non-billet alternative. OK that’s out of the way; sounds good, makes perfect sense, long overdue, pent up demand, solid program goals and principles, only thing lacking is execution (no not mine). As always, the Junior [entry level head] was to be completed First followed by the release of the Senior Max-Flow EQ head. At that juncture, production capabilities to keep pace with demand were planned and anticipated program objectives. I had hoped to be past all the foregoing sometime during the 1St quarter of this year 2019. Obviously that has not happened and I am VERY disappointed to even have to report that reality to you.
WHY?? would be the next logical question from any astute observer of this Forum!

Senior Head update: JUST this week I Finally Received a finished Senior head with purported near program goal of 260 CFM intake port flow. After you have read my entire sequence of statements above, it should be patently obvious I will not accept anyone’s word written or spoken as Gospel at this juncture. Therefore, the much needed Senior head will not be released for production until I can verify every port on the one in my possession as per program objective and verify every combustion chamber Cc for compression ratio calculations. When verified, replication of the Senior head will have to be sourced bearing in mind that this head in particular, lends itself to full 4 or 5 axis machining which is the direction I am pursuing at present Surely much more than you expected for a update and far from routine I might add. Your thoughts and comments are both welcomed and anticipated. I will take this opportunity to quote the one and only Albert Einstein who I had the pleasure of meeting in person as a young lad. GRAMPS

What are the problems that you are having? I’m too far away from FL to be of practical help, but I have good connections with professional engine machinists, including a few CNC porting shops, from all over the USA. Maybe I could help you connect.

"Max_Effort" Thanks for the referral offer as one never seems to have enough 'prospects' in the quill. FINDING and selecting New prospects to achieve most anything is something I love doing, as it requires a combination of skill sets and decision making. Once my list is boiled down the process of deciding just who is going to do what, where, and for how much begins. Not an assignment for the weak, timid or overbearing. It takes a delicate balance of judgment and stick-to-itiveness to pull this off. Then being able to KEEP this new resource motivated, compensated and interested are all factors I have had to deal with and will continue to face as I “make it happen” with this ultimate challenge Gramps has promised to COMPLETE.

As you know from Bruce’s last post, some of the important work relations fell through as they could not hold up to their commitments. New and more promising connections have been made, some through long time friends of Bruce.

The program is back on course.... but because these are both new and promising connections, we won’t know for sure for another month or so. If all goes well, it will go very well.

Grampa positive on progress and new resources. Should have gone this route at the get go. It's amazing to me how many people will step up to the plate to help with MY CAUSE. End result will be considerably better than anticipated with unsurpassed QC and consistency of Head to Head production runs. :beer: Bruce Sizemore

Its Gramps travel weary since my last post (seems like months ago with 5K plus in road miles to my credit). Slow but sure is my best update on the 3-head projects. Yes I could start banging out heads fairly soon, but I want to give you the utmost in both JR and SR versions. You deserve something unique for your patients and loyalty in trusting me at my word. the overall plan now is to only offer heads that are difficult to duplicate (unless you have access to a 4 or 5 axis machining center), then you need to find digital scanning equip like the "Big Boys" use, convert the scan to code that matches your machining center, etc etc. In my travels I even visited the Roush facility to discuss my projects with a few friends there in "high Places" [what an eye opener]. enjoy your summer Gramps will be BZ so information will be sparse. Bless you all. Bruce Sizemore :thumbup:

That sounds wonderful. Before you depart on your engineering adventure, are there any updates on dyno results from what you’ve done thus far.
Many thanks
