Intake set-up

Look what I got today, I bought 2 of the 97 carbs from Vintage Carburation Technologys ( Jere Jobe ? )
Never used after rebuild.
Fits perfect on the Thickstun PM7 intake and 30 something oilfiller tube and the early 6V generator.
I don't know if I use this set-up or the Edelbrock Super with dual LZ carbs and a 40's 6V generator and the 40's 59AB oilfiller tube.
-Anyways its so nice see one near get a tear in eyes.. ;- ))

The LZ carbs are push-throttle. You'd use them if they were turned 180-degrees around like on a Hexagon Tool intake.

The Edelbrock Super would use the same 97s as the PM7.
 
You have a hard decision to make, both of those intakes are nice. Kind of depends on what era you're going for. The tall manifolds were just about all gone by the end of the war. Most hot rodders switched to the low manifolds when they arrived around 1946. if you're building a pre-war hot rod, I'd use the Thickstun. The Edelbrock Super intake is an excellent low two carb intake, probably the best two carb intake, but there's no room for the generator on it, it's going to go on a bracket on the head.

My dad's roadster I inherited has a low two-carb intake with an alternator (icky) in the stock spot. I don't like it, so I was going to switch to an Edelrock Super intake but it's an 8BA and as far as I can tell they didn't make it for the late model flatheads, at least I haven't seen one or any old ads for one. I don't think the Edelbrock Super exists for th8BA. He bought the '32 just like this and then never did anything to it but put '39 taillights on it. It's a real '32 roadster, red, just like the one he had when he was a kid in the 50s, he even had a late Model Merc in it like this one he bought.

Very nice intake set-up, Hank.

Flathead Fever: Correct, Edelbrock Super is designed for pre-8BA engines. Doesn't mean you can't use it. Just need to think about venting. Offy and others did make "Super" intakes for 8BA's.

Thickstun PM-7 came out after the war. Edelbrock Regular was also a post-war tall riser intake and stuck around until the late '50's.

The first generation Thickstun was a pre-war intake.
 
Tommy Thickstun ded 46 but he did the intake until that end Tattersfield took over ( same cast )
I read this hi-rise came late 30’s, Weiand etc, but for some reason my ideas has to become the years after war 45 to max 49 when the 8AB came out.
In Bell Autos catalog 49 they show the Edelbrock Super and the 40’s generator on the head and a Kong distributor in a engine.
I’ll just fell to to that look, so I find a Super intake, replaced the Scintilla ( 8AB set-up ) for a Kurten.
So the PM7 went to display but today this 2 very nice carbs showed up as I could recist not bought them.
Nice look but I will use the Super in car.

Intresting.
Tell me more on the Lincoln set-up LZ carbs !

I have a tall Edelbrock Regular intake sitting out in the garage, my dad paid $35.00 for it with two 97s in the 1970s. It's a neat intake, I don't see those very often.

I have most of the SCTA programs from 1938 to 1951, Lots of neat hand drawn old intake ads in them. I knew all that flathead history pretty well and then I had a stroke and have forgotten about half of it. My brain is ready for an overhaul.

Flathead Fever, please don't think I was jumping on your post. I'm just a nut over the history of all this stuff.

What is the advantage of having a tall intake carb mount?

Jim:

I've read a few different accounts. A fair number of the early intakes (Davies, Alexander, Jack Henry, Eddie Meyer) used tall runners and were two piece castings.

I've read it was easier to cast them this way vs. a more complex single casting.

The other thing I've read was the logic of the time was to help atomize the poor quality gas by pulling it under vacuum down a "ram" tube into the intake ports.

By the late '40's/early '50's the design fell out of favor for the Super 2X2, 3X2 and 4X2 intakes.

Jim,
Good question.
Some told me here in Sweden the Hi-Rise was better top RPM and the lower ( as the Super was better at TQ.
Me, I has no clue on this engines how they work in nostalic trim.

-A wild guess for me is the Super is a better intake that the PM7 in both lower and upper RPM, and both is cool looking in their own ways but the Hi-Rise is really screaming old Hot-Rod.

I had a E&S direct port X4 ( boat racing ? ) but could not get it to work on carb linkage vs the L&S heads watertubes, so when I saw Hetfields ( Metallica ) 32 roadster that had L&S heads and a Hi-Rise I traded my direct port to this Thickstun.
Then I saw the Super intake and it did 'feel' more late 40's so I think that style with the Kurten front distributor and generator at head overplayed my idea on the Hi-Rise and a Scintilla. As I had the magnet set-up for 8AB I needed 8AB pumps ( did not fell right ) so now I'm Ok with the Kurten Lincoln V12 but look for a Kong, so let's see.

I like my L&S heads and according to what I read it was sold to Georgia in ca 1948 so my was made in Burbank, Ca so time era is good and I think idea was hi comp and more water.
Now I'm in the idea to try find the cast iron Kogel heads, and as I think they was around 46-48.
The L&S is nice look and the Kogel is rather 'ugly' but I feel a big cool factor has them on.

Talking on intake.
Question.
The Thickstun intake had about 64 mm for mount the generator, and my both generator's early and later 6V has a 64 mm mount face - but the Edelbrock Super intake has a 58 mm mount for a generator (?) 58 mm is ca 2.28".

If you want some "useful" data on the Thickstun intakes, read JWL's book. He had a love affair with this beautiful piece of fabulous engineering., He studied, tested and recorded his findings with a borrowed Thickstun. He convinced me that the money needed to purchase one these was well worth it. i did find one, online, and had Charlie NY rebuild two 97s specifically for this setup. I have not tried this setup yet. My poor '47 is on injured reserve. I am working hard to get the'47 back in the game and give this setup a go.
Thank you for posting this topic. Read JWL's book!
 
If I’m correct on what I has read Phil Weiand used his pre-war Hi-Rise 1948 and was fast.
I guess the early Thickstun look like that, but if a PM7 is better than the older Weiand and Edelbrock I guess hard to say.
-Will check that book up.
 
Hot Rod Magazine / Motor Trend / Peterson Publishing did a series of dyno tests of flathead intakes on a hopped up flathead several years ago. The best performing two carb intakes in that test were the Edelbrock Slingshot and the Navarro Racing. Arguably the best looking intake was the PM-7. The article is still findable on the internet, you just have to work around all the advertisements stuck in it, available here:https://www.motortrend.com/how-to/hrdp-1301-flathead-ford-intake-manifold-smackdown/

Weiand also made a tall intake. I saw one at a guys house, but he wouldn't part with it, although he wasn't going to use it.

Yes, the Weiand tall is a pre-war intake. Similar in runner design to the 1st Thickstun version.

Some flathead history. The Weiand intake inspired Barney Navarro to design his "dog bone" intake after running the tall Weiand. Once the sun went down, his car kept getting slower and slower. Opening the hood, he realized the carbs and intake were freezing over due to poor heat exchanging.

His dog bone designed allowed the owner to have heat when needed and then a "cold" intake when racing.
