Definitely great to see this one happen John. Hope to see that manifold display case/combination bar in the veranda one day! Any idea of the last year/month these might have been used?

My guess would be that it was used until the first 36hp (Jan 1 '54?). Again, it seems odd that there was a "701E" style, 25hp/26mm intake that came after the Jacketed K, then this '53 only intake, then the real 701E.

It is almost like they were playing around with a better design for heat transfer between the heat riser and intake runner, then went back to the old design.

Also, it could be that it was just another manufacturer too.

I did find in my box of intakes last night that I have at least 3 of the intakes with the "figure 8" casting (deep grooves cut front and back, like Bob has and like my original one in the first pic), but they are 36hp/28mm. Two of them are even marked 701E, one has no markings...

Now media blasted, ready for masking, paint and baking. The "701E" intake there is one I milled for 25hp engines (anyone need one?).

(The right side heat risers on the zwitter intakes are not "overbent" it is just the curvature and angle of the shot.............)

Excited! I think you have me down for one 25hp manifold

Yes Matt, the two shown in the pics are spoken for. One is yours, the other is for well known part hoarder who lurks here and whome I've owed this intake to for probably 2 years now.

But the other one that is a standard 701E 36 hp intake has had its endcastings milled for use on a 25hp engine. This would be a good subsitute for the 701E style 25 hp intake that was used after the Jacketed K was phased out (mid-late '51), but before the '53 only.

The unknown is when this zwitter/53 only intake was used. Probably until the 36hp engine in '54, but not sure when it started...

These are done. Painted and baked.

This one has some oil that has "bled" out of the casting during baking. Some solvent and it wipes right off.

I actually mask off the whole casting before spraying. This is very painstaking (getting all around the pipes where they enter the casting on the ends) but it gives a nice clean look, and the aluminum looks like aluminum.

If you wish to not block the heatrisers there is a way to weld the inside of the riser where it touches the intake pipe.

Instead of cutting the pipes square, start with a square cut, then cut off part of each pipe at a 45 degree angle, leaving just the part that touches the intake pipe square. Then you have access to the inside of the heatriser for welding. After the inside part is welded, fit a pie shaped section to the now "V" shaped hole and weld the outside. Voila, full weld all around.

Good tip! I might have to give that a try next time. Thanks..

I have seen one of these manifolds on an unrestored 54, maybe it was an early 55 even, but it definately was'nt a 53 or a 25hp, it was a beat up red beetle at a show in Milan Michigan in the late 90s , I always thought the late '53 25ers had the tall fat heat riser that went up towards the carb with the 25hp style K runners, an original 53 carb had the accelerator pump but no vacuum port on the right rear since the engine still uses the 383 centrifical dist.

[johnshenry]

I have an original one of these also, and it has 36 hp endcastings, so it seems they were used on the early 36hp engines as well.

John, one of these days we all need to put together a book or something on what is an "authentic" VW restoration, of course engines are a real sore spot lacking any credible info in any book I have ever purchased, gets pretty tired looking at book after book showing 36hp engines in splits and labeled as original, of course there are ranges of what is "correct" and a lot of randomness as the factory experimented with this and that new part and using up old stocks, but it has to be possible to make this happen, I know there are Corvette guys who have all the correct bolt head markings casting numbers and such listed in their books, why are VWs such a mystery, even a book with just actual ORIGINAL unrestored cars only would be a big hit with me, I am always impressed when I see an oval or a split with a front hood prop with the primer still there where the prop overlaps itself, I dont think I have ever seen anyone attempt to duplicate that, also unpainted shiny headed bolts holding the hood hinges on bug me too, and I have taken apart a few original 25 HP engines which used gunmetal blue sheet metal screws everywhere, not a shiny one to be found, its things like that that impress me, not a clear coated 42 coat paint job, just my 3 cents

[johnshenry]

I've been working on a "Split buyers guide" for while now, and yes, I intend to spend a lot of time on the engine details. I am working on a format to track several part changes along a timeline. The details in the 25hp engines alone are incredible, and you are right Bill, there is virtually no documentation on them....

John,

Sorry to open this back up, but since you have my intake and it's only a month earlier than Bob's, are you able to verify the markings that were on these 53 only manifolds

Eric

It probably highlights the number of changes occurring at this point in production. It seems really tough to pin down exactly what was going on during this transitional period. Imagine from split to oval, from 25 to 30 horse and the 1000's of other changes going on.

Here you are (We) trying to figure out exactly what and why 54 years later????? No wonder it's tough.

Thanks again for your help John,

Eric

[my65vert]

I have a NOS 701E intake, have no use for it. Is it worth anything?
