Ford SOHC Hemi? crossflow cylinder head

Back around 1971 or 72 this was my High school driver. A Ford 67 Mustang fastback, big 6 240 block with a 300 crank. The cylinder head was a crossflow aluminum single overhead cam and I am pretty sure it was a Hemi chamber but as you can see from the picture the spark plugs were not in the center of the chamber.

Needless to say, it was a beast of a head. I always drove it without a hood and had many car guys scratching their head when they would pull next to me. Not many people had turbo's or propane back then, not to mention the wild looking cylinder head and a skinny high school kid driving it.

The pic shows it when my Step dad and I were mocking up the Air Research turbocharger and Impco propane setup. I had to fabricate a custom exhaust manifold for the turbo but it did come with the intake manifold. I only had this for about a year and from what I can remember it had a fairly mild cam because it was tame at idle but the turbo liked it.

From what I remember there were only two of these made by Ford. They were made for the Big 6 at Dearborn.

I used to have more pictures of this head and another one just like it but I haven't been able to find them. My mother took pictures of people whereas my step dad took pictures of engines. When she cleaned out the crates of pictures they had collected over the years, the engine pictures got tossed and I was lucky to have saved a few of my personal rides.

That's cool. Thanks for posting. Not sure if that is a 240/300 short block under it. Distributor should be on the driver's side where the carb mixer is. I wonder if Ak Miller was involved in the build?

It appears to have spark plugs on the driver side, that seem to have wires going below the intake.

Either way it's cool as F***!

Does the intake charge make a 90° turn upwards at the head? Speaking of head, that is pretty narrow for an OHC head. Seems to be tightly packaged, and perfect for boost.

Yes, Ak Miller was involved, he was my step dad. He married my mom when I was 5 years old. He worked for Ford as their performance adviser in the 60's. Ford would send him cars and engines to hop up and get them in magazines since he had ties to Hot Rod and Motor Trend. He loved six cylinders and it rubbed off on me.

They sent him these two heads to play with but there wasn't any push to do anything with them. He also gave me his 67 Mustang around this time and we put this head on the engine that was already in it.

I don't remember how tight the distributor fit was but the head was much taller than the standard head. I'm pretty sure the intake ports didn't turn upwards but I can't recall any details about it. I do remember the valves being very large compared to the standard head.

I had to give the head back to him and I put on his 240 head that he ran at Bonneville. He didn't do anything more with them and eventually sold both of them to a drag racer.

:beer: JPierce looks like it was a very fun project, thank you, that's a great story! I used to work at the the Ford assembly plant (Rosemead Blvd. & Washington Blvd. in Pico Revera, Calif.). Over the years and A few times on my way back home after work, I stopped into Ak's shop to see what projects he's was working on. He was a great engineer and I really enjoyed reading about all those Ford Six's he built back in the 1960's and 70's. I have been hunting a couple years now for one of those articles he did on a Maverick six buildup compareing it to a Mustang back in 1969 or early 70's. (y) :nod:

I still have the shop but I lease it to some of the guys that used to work there under Jack Lufkin who was Ak's manager. I went with Ak to Irwindale drag strip with the Maverick when it had a mild turbo setup on it. I think he converted it to propane at that time. He just wanted to run it with the street setup so boost was only about 5 pounds since that was his daily driver for a while. Got it down to 14 seconds flat but the 1 wheel drive killed the launch.

Here's a picture I found on the web of his 250 when he had a Bosch fuel injection off a Mercedes. I can't tell if this was in his 65 Mustang or what but the engine ended up in the Maverick. He had this same pump on his 300 six.

Wow, that's got to be it. 400/200 CFM, I guess those those valves were just as big as I remember. Sure wish he would have held on to those. Magnesium valve cover, that thing was even more epic than I thought.

Here's a couple pics of his 67 Mustang with the Bosch injection. This is when it had the factory light green metallic paint. It was painted school bus yellow later after I smashed up the rear end while learning how to drive in his shop parking lot. Worked out well for me.

Here's the 67 Mustang with the big 300 and webers at the 67 Bonneville meet. I think he ran 150mph with this. Drove it up from southern California, raced it, and drove it home.

Its WCG commenting on above. I am curious as to where on this planet you lived when you had this unique Scientific Research Lab prototype in your 67 Mustang. Please elaborate. Gramps

I lived with Ak and my mom in Whittier California. Photo was taken around 1971-73.

That's Bosch CIS (constant injection system).

It's fully mechanical injection. There's a diaphragm that measures airflow and varies the amount of fuel flow to suit.

Tuning them (and remanufacturing the units) has become somewhat of a black art.

Jay Storer was your Step dads greatest advocate. Jay passed on in 2017.

The rediscovery of the technical work Ak Miller did was well underway in 2014.


For me, it started in 1985 when I worked as a garage laborer with an ex Ford service technician. I worked propane, and whammo!, in comes books by Ak Miller and Impco on propane, and how to link them with Throttle Body Injection EFi and the feedback Carb. All of it was exceptionally well explained in the Impco Technical Service bulletins. That info was Aks before he went to OHG or Century as an adviser.

After seeing what he did to produce the 255 Propane XR7 Mercury Cougar Turbo and 2.3 Factory Propane turbo cars in the 1981 Granada press conference cars which are in the 1985 Propane Perforance book, the guy was a "bit of a whizz kid". Those cars came alive.

Last post of the five had your Bosch injected engine. I think I downloaded the photobucket copies if you cannot see them.

The Red 1981 Capri actually belongs to my buddy. It was Ak Miller's personal vehicle back it the early eighties. I had a chance to buy it for $7000 but passed on it and bought a brand new 1983 Capri L 5.0L which I still own today. The 81' Capri is a twin turbo 351w with an AOD running 12 PSI of boost on propane. I ran a similar setup but with a 302 and single turbo. I am currently building a 347 with a turbo but switched back to gasoline just recently.

This was Ak's favorite setup for his 300. He must have got the tune right because I remember it being very smooth and responsive and he kept it on for a couple years. A lot of guys thought AK would have the most radical setup on his cars but he liked silky smooth wide power band setups.

Thanks for the links, that was a stroll down memory lane. Ak started researching Propane and met Herb Hills who owned Impco and was one of the nicest old guys you could ever meet. They became close friends and Herb sponsored a lot of Ak propane racing exploits. OHG was short for 'Over the Hill Gang' and I think Herb joined together with Ak when they started that company.

Hi JPierce, From the shape of the towers, firewall, and cross flow radiator the 250 looks to be in a Maverick. Interested in the Combo Hilborn / Bosh injector pump Ak used on the 250 wonder if it’s an Aussie 2V head or just the log cut off.

Spent lots of time at Irwindale was close to home, also at Lions, Fontana, and Orange County drag strips racing my cars.

Glad to hear that you still have Ak’s shop a lot of history made there. Thank you for all the pictures they are great! (y) :nod:
