Thanks Lunatic Fringe:
You can imagine my surprise last September when one of my Ford contacts "thought" he might be able to locate my Pinto , which only happened because I attended the 50TH anniversary of the Cobra Jet Mustang at Summit Motorsports Park in Norwalk OH last July. He tracked it down and found it in a warehouse were the Don Hardy Chassis “gasser” had been parked since 1982 yes 36 years not seeing daylight. Hard to believe and one of those Bucket List items I never thought possible. Now we will soon have a rolling test bed, with a familiar feeling driver seat, updated chassis where necessary and our BSX-Flow cylinder head I predict will make 600 HP NA. 2019 should be quite a YEAR for we Loyal Forum Members.

:santa; Merry Christmas, Happy Holidays and Happy New Year :beer: to ALL.

Gramps welcomes you also and predicts you’re quest for Big Six knowledge will be richly rewarded by avid participants on this Forum. My lack of posting in 3-weeks is a valid point and requires a brief explanation.

FOR ALL OUR FORUM Followers: Overall progress on the (3) head development program has been very slow in the past 6-months, due to various circumstances NOT all within my control. Additionally, program directional changes, equipment purchases, development personnel issues, Financial expenditure limitations and my own insistence on quantifiable, quality and goal achieving standards have all played a part. I have never been a “slap together good enough person” which is sound Ford schooled logic especially applicable to motorsports excellence. BUT there is light at the end of our proverbial tunnel.


Junior head is finalized in design and configuration options offered. Several orders have been received are in process and will be shipped to customers upon final assembly and my personal 1-by-1 Q.C. verification. NOTHING will be shipped without my involvement and personal oversight.
Senior head is nearing final flow/design process and should be 100% goal oriented 260 CFM by months end.
Dyno testing of a fresh build (local Customer) Junior head 4BBL 4.9L, is nearing final assembly and optimistically will produce copious amounts of mellow sounds and power with published results posted by yours truly.[size=150]

[size=150]ALL please note: pmuller9, wesman07and I will TRY to answer all PM’s regarding our Development program & products offered. WE cannot be a separate forum resource for general build questions such as ‘which cam should I go with’. In most instances 95% of similar questions have been asked and answered elsewhere on the :help: Ford Six Forum. I strongly suggest using the SEARCH feature provided to narrow down individual parts of your multiple question PM’s some of you have been sending to us.


I intend to see this through!! ALL of you have my personal commitment to that end.

Should be a great New Year the Good “Lord willing and the Creek don’t rise”.

Thanks for the update!

I have a burning question that has been in my mind. With all the efi head issues with cracking, how do you see this being circumvented with the wider valves and therefore reduced space between them. I understand that the EQ head has more material available in it, but...
I also understand that these setups won’t be for high mileage use as well.
Thoughts?

Thoughts?

The stock head has induction hardened seats where the heat from the exhaust valve directly disipates to the cast iron.
The EQ head comes machined for seat inserts so more material is needed in that area so there is room for the insert cutout.
The exhaust seat itself is less susceptible to failure from heat cycles and does a better job dispersing the heat evenly back to the cast iron.

If a JR or SR head is set up with the proper rocker arm geometry and steel roller rockers and considering there is hardened exhaust valve seats to minimize valve recession, there is no reason why the head on a well maintained street engine won't outlive any other head.

One more question. I’m building manifolds using my efi head. I’m assuming that the EQ head has identical port shapes and dimensions to mine. Please verify.
Thanks

The JR EQ head will have the same port shapes as the stock head.

The SR head intake ports will be larger at the sides and top. I do not have the dimensions.
I will see if Bruce has final dimensions.

I heartily agree and second that. I'll be placing my order in a few weeks, once I'm certain my company isn't going to close my office. My build is going to be the exact parts that Gramps and pmuller have coached me. I met a machinist at my church that has all the tools, and room, to help me with the build so I'm getting excited.
Thanks again for sharing your knowledge and not belittling anyone for their lack of knowledge(I include myself). :thanks:

Exciting times.
Pmuller, I consider your port shapes/dimensions for the Sr Head confidential, so I don’t expect you to post them here. It would be useless to me for a manifold unless I knew the exact spacings as well. I’ll wait.

Gramps can assure you three and everyone else interested in our 'best of the best' Senior head This [enlarged intake port entry shape] will be rectangular with rather small corner Radiuses’ aka Radii BUT I am working on the possibility of modifing the Mr Gasket and or Fel-Pro 300 performance gaskets as a possible (shipped with the head) option rather than go the more expensive route of getting with the "Cometic" gasket for one-off special run. In both cases the stock ford port to port centerlines will be maintained with little if any offset so that you can easily match your aftermarket intake manifold with hand grinding on a Sunday afternoon, no AM to interfere with church going. I again am in hot pursuit of cost saving bundled machining options, for set up time cost savings and will have finalized revised JR and SR base head pricing, in net week or by my personal last date goal of EOM 1/31.

The pricing on the JR head has been finalized as promised. OK maybe a few minutes late.
See pricing in the "Buy, Sell or Trade - Big Six" section.

Congratulations on such an awesome achievement. 300 fans will be forever in your debt for making a new head and selling it at such a reasonable price. I can’t even imagine all the hard work and dedication that went into this project. I just wanted to say thank you for such a gift to the in-line world. I will definitely be ordering a head for my engine.

Thanks for the kind words. Don't get that too often as very few members fully understand the scarifices and financial hurdles I and others have had to endure.

Paul , Wes and a few other forum members have been privy to all the goings on behind the scenes.

Dyno Testing Update:
Yesterday Saturday 2/2 Had a great meeting with my “Pal Al” machinist, dyno operator, engine builder, fabricator etc… and sometimes even operates the flow bench he owns that we did our primary FB work on during most of the early development period last year. As my confident Pmuller9 just stated we are waiting the arrival of our spec’d custom grind Crower Hydraulic camshaft. The question posed by
Sandboxer post# 376 and answered by Paul Muller #377 below:
That’s a great price. Was there a plan to dyno an engine with this head configuration?
Pmuller9 Answer - YES We are just waiting to get the custom camshaft so the engine assembly can be completed. Things always go slower than expected.

Both Al & I agreed yesterday to not only fully Dyno test this in-house customer JR head engine but to simultaneously test and compare a New complete EQ EFI head with no porting, stock valves etc for improvement results that will be empirical NOT guesswork. Using this methodology, although very expensive, will give all of you data you can “hang your hat on” and plan with.

If this prompts you to chip in please do we need every dollar we can gather. :beer: GRAMPS

Haven’t been on in awhile..Very long read to this point! Riveting material, excited to see the sr head when it’s done and $$$. 260cfm would be terrific! It Was unnerving hogging out a head after slicing another up for comparisons.

Sorry if I missed it but will there be a long Chevy valve version for the guys running modified pushrods and so on or just bare castings? Same goes for stud converted heads from pedestal? Again I’m sorry if I missed the post that contained the info that I’m asking. As I said a long long read! And thank you Gramps and friends!
Best of luck,

Both the JR and SR heads use the 4.910" long Chevy valves.
The SR head is set up for the Chevy 1.94" intake 1.60" exhaust valves so you can use the longer 5.010" valves if needed.

Hey Gramps
It’s nice to hear from you. I was wondering if you had put the jr head on an engine yet and if so, whether you have any feedback. I know you were waiting on a cam or two before a dyno run...
Thanks

Likewise, Sandboxer:Yes Crower cam and valve train have been sourced.
As I write this 3/2/19 the final machining touch is being put on the block which is probably unnecessary but the engines owner "wants it 100% right" and has decided to go the ARP main cap stud route, which necessarily includes line honing. After that final operation AL and I will assemble the engine and prep it for the Dyno. I have purchased a complete EQ efi stock head assembly for direct comparison on the dyno, specifically how much the ported JR head will increase over the un-ported EQ equivalent.
My extensive Ford training comes in handy on numerous fronts, agree? Even our professional RE practice motto gives you a good idea of where Gramps comes from... which is "Results ALWAYS speak louder than words" Our competitors despise it but our customes love it. :thumbup: :beer:

Hi Gramps, that's interesting! I will add a few things to the wish list if Ford should want to support us,. It would be nice to see some new improved 300 blocks and also the rare 300 SVO version blocks reissued, a fully counter weighted Forged steel or Billet crank would be nice too. Good luck :thumbup: :nod:

Bubba: One more trip to Sarasota Bradenton Motorsports Park this coming Friday. Ford contacts are NOW well informed about my overall intentions and that of our Forum members in general. They are blown away at the continued level of entusiasum in a production inline engine that hasn't seen the assemblly line in 23 years!! Why all the offers to help?? Because I never 'burned any bridges' or bad-mouthed any of my former Ford less than cooperative associates or sometimes refered to as 'necessary evil' prevalent even moreso in todays corporate America. Sorry for the rant. :bang: BACK on TRACK.

Since the Jr u-flow head is completed , in permanent final port and chamber configuration, with documented #'s available for ALL to see; MY COMPLETE FOCUS is now on the Senior ass kicking higher Max-Flow counterpart. The Ford contacts have suggested I (WE) strongly consider only offering this more complicated and precise Senior Head in FULL CNC format. This will take some doing, additional development time and resources, something I personally would have a severe migraine from if I try to tackle SOLO. What are old friends and x-Ford racers for? Jummping in with all "feet" to save our effort in the 100% fool-proof way. So there is the GOOD NEWS. Lot's of planning, more Development Funding, air travel and out of town business trips for GRAMPS but what else would you expect but a Max-Effort from this Old Worldchamp. Stay tuned and visit the piggy bank if you can this is really exciting :idea: . :beer: :wow: :help: $$$ and Pray for my sanity. :D :thumbup: :party:

Gramps is happy to report that our FIRST customer Dyno engine with the Jr ported head soon to make noise and be compared to a recently purchased complete stock EQ efi head. As AL (Machinist in pic) readies the final components this is a long awaited plus for the entire program. I will release full specs on the engine so those of you who want to duplicate this assembly, with our purchased JR HEAD and your components>> know what to expect. Close up photos of the oil pump modifications you will have to acomplish [if you go the Main Stud route] will follow. We could really use more help now as just the direct EQ head comparisson is a $700 exercise BUT that doesnt even include the extra dyno & assembly/re-assembly expenses. Here is the link for your consideration. Be happy with us. Warmest personal regards to ALL. Bruce Sizemore Sr

Given the anticipated wait, I'm leaning towards putting my current engine back together and in, breaking in the new cam with the same 390 carb, then converting to Sniper TBFI, then having it dyno'd, and just drive it for a month or whatever.

Then swap the Jr on when it gets here, and go back to the Dyno shop for the head swap comparison. The current head is a moderately dressed '82-'83 carb'd.

Anyone with Dyno shop recommendations in the Denver Metro, please feel free to share. Cost will likely be a limiting factor.

Don't forget that the JR head has at least 10cc less chamber volume than the Carburetor head.

Try to negotiate time to optimize jetting at WOT and also optimize timing at WOT. Remember to use knock-free fuel and then be cognizant of the potential for knocking on your post-dyno road checks and adjust total advance as necessary.

I ran a primitive form of water/meth "injection" in the past.

This time I'm going to be running modern high pressure water misting injection. I'm not overly concerned with more compression, detonation or knock.

Water/meth injection works great.
Until it doesn't.
I'd maybe run a dyno test both ways and have a fall-back schedule baked into your software.

Many have mentioned cost and how it's so expensive, blah blah blah.

I just ran across an example or "comparison" of what you pay for porting a FORD 240/300 head WITHOUT THE HEAD factored into the price. YOU HAVE TO SUPPLY THE HEAD. Assembled with springs, retainers, guides, valves, PC seals and screw in studs: $1350. Just the machine work and NO PARTS: $1000. Price a NEW Engine Quest 300 cylinder head on your own, they aren't cheap.

I'd supply the link, but don't want to upset people. You can easily Google it.

:nod: :wow: Great Stuff GuhFluh: Looks like Gramps Jr & Sr heads will be "the only game in town". Dyno results will prove their worth. Just pray that Gramps stays out of the "loony Bin" at least until the project is completed.

I think the price of the heads are very good. We only have to buy one head for the 300. Look at the price for a pair if medeocre 460 heads for example. Going fast just isn't cheap.
