View Full Version : Studebaker to SBC Intake Adapter Plates

04-24-2017, 10:48 PM
I am going to make adapter plates toallow bolting a SBC intake manifold the Studebaker V8. I know I am off the deepend for starting another project but it is just a continuation and refinementof Jeff Rice's adapters on the Weber motor. Those adapters and the manifold areunique to each other and can only be used together. These new ones will allowmost any Chevy I intake to be trimmed down and bolted on. Jeff's parts areaccurate and both the same but no drawings were made. I took carefulmeasurements of them and had a friend at work create a 3Dmodel. I had the 3Dmodel printed in plastic and poof, instant adapter including threads. Here aresome photos of the plates with gaskets. The port /bolt alignment needs tweakeda few thousandths. If I can sell 10 sets I can sell them for $330.00 a set. Iplan to buy two sets myself and I can stand to sit on a couple of sets for awhile so I need to see what the real interest would be in them. I can drop theprice to $300.00 if I can sell twenty sets. The plates will be 5-axis CNCmachined and have stainless steel thread inserts for the GM side. I will doanother 3D prototype with the tweaks before going to metal. Lead time would beabout 8 weeks after I pace an order. Let me know your opinions, either way.

Looks super.
Wouldn't it be neat to be able to print them out of a heat resistant material and just put them on?

I guess the driving thought behind this is the common availability of Chevy manifolds? I have never studied the difference between Chevy and Studebaker pieces. Will the thermostat housing area and distributor area just be cut off of the Chevy part?

That looks pretty cool. My question is, will it fit under a C/K or Avanti hood. The manifold you are using looks a little high. It is nice to see folks working to give us options for our Studebaker engines. I'm assuming you will whack off the front cooling passage and the distributor hole....

This company is right around the corner from me...

(not cheap :()

I have a manifold trimmed to remove the unneeded GM accessories. I started with a Weiand "Street Warrior" dual plane. It needs some TLC but I think it looks good for the rough cut. This is an example of one of the many opportunities there is to put a GM SBC on the Stude. I will be at the South Bend meet on Wednesday afternoon and all day Thursday, maybe Friday? Jeff Rice has been gracious enough to let me display the adapters and some other "unique" past projects of mine in his trailer. Hope to see you there.63773637746377563776

The idea is that there are many possibilities with the adapters.

Lookin' good!
See you at South Bend!

I took the adapter plates to South Bend for the internationalmeet. There was some additional interest in them. I have decided to lower theprice on them to $300.00 plus shipping for a set. This is based on payingmyself minimum wage to install the inserts, clean them and package with onlyadding a 3% mark-up. If I gave you my email address at the meet and it is not workingit may be that I gave you an incorrect address. PM me for the correct one. Letme know if this price reduction adds any interest. I would really like to haveall ten sets spoken for before I go to metal. So far, I have commitment for 4sets.
I took measurements when I got home to compare the height ofthe adapted manifold to the stocker I came up with a difference of 2.375”higher elevation. This is based on a 4.50” tall SBC intake. 4.00”ers are outthere. I found a SBC tri-power from the 60s on EBay and it is only 2.50” tall,equating to only a 0.375” gain in elevation. There are some older manifolds outthere that are lower but not “as low” as stock.
If you are looking for a straight bolt-on for a 53 - 55 C/Kthat will fit under the stock hood, be cheap and require no alterations…… thisis probably not for you.
If you are willing to experiment with some differentcombinations it is possible to get it under a Hawk hood.
If you are a serious racer or building a Stude powerednon-Stude hotrod and are not too concerned on hood modifications then these arefor you.

PM sent.......1 set for me......

Are you drilling them for early or late manifolds?, 86 up i think.

05-11-2017, 09:23 PM
The plates are made for GEN I intakes, pre '86. There are more low intakes out there in the early intakes.

PM sent.....I'm good for 1 set.

I have 6 commitments for the adapters which includes 1 set for me. I also have 2 tentative as well. I am going to make one more sales pitch with the photo from the international meet doing my best Vanna White demo. I would like to have at least 8 of 10 spoken for. I'll go with only 6 sold if need be but it will cramp my hotrod budget. :).

05-15-2017, 09:27 PM
Hmmm......hadn't thought about it, but the manifold adapters open up a whole plethora of blower manifold options. ;)

And, I don't remember Vanna White having a mustache! :ohmy:

Yep...opens many new posibilitys.
Just do go too large a runner.

I'm signed up for a set.

It's too bad Studebaker designed their heads with the middle 2 exhaust ports siamesed into one, thus reducing the breathing ability of the engine. That would really have opened up the engine to hot rodding performance possibilities.

And..., one gets an Air Gap manifold without having to buy a..., Air Gap manifold! :)

Nothing is ever new, but how you get there is...
These Stude/Chevy adapters have been around for a long time. There was an ad in Turning Wheels way back in the early 1970's.
Just is they 'were' a pita to make. Even the Mopar adapters were a pita.
Now... John took the newer technologies and is bringing out a product that looks superb.
Having fondled his prototypes, I like the concept. They will be an interesting addition to the Stude performance world.
I look forward to seeing some aluminum ones..
Looking good, Jon!:!:

Paul / r1lark,

Weiand makes a very low profile supercharger manifold for the SBC. If you custom dropped snorkel you could probably close a Hawk hood on one. You could really go off the deep end and add a "POTVIN" front mount supercharger. It would require some fabrication to replace the Chevy timing cover mount but it would not be all that hard.64220642216422264223 The upper picture is the Weiand, the next is the current kit Moon Equipment still sells. The other two are a scale model and even though it is on an SBC it would still fit on a Stude in a Stude. I am tempted to start production. :)

To all that said they would order here is an update.

I sent a purchase order to the machine shop for one pair in metal. One set will cost me over double what I am charging but I want to double make sure they are right before ordering 10 more pair, (I will not increase your cost). Once received I will immediately confirm their fit and if all is well, order ten more sets. I know this is taking a while but they need to be right. If you want to see photos of the progress check out the racing site. Of the 10 sets, 6 are taken, 2 tentative, so theoretically 4 sets are still available.

Great, thanks for the update.

After some tactful persistent prodding the machine shop will start cutting metal on Monday next week. I should have the "real metal" prototypes by the end of next week. They are close enough I can go pick them up. If all is well with the fit I will post pictures and email all those that committed to order to confirm that they still want them so watch the forum the weekend of the 15th and your email. I should be able to order all the sets on the following Monday. :)
