Technical Did anyone make a 331/365/390 Cadillac 6V71 Intake

Serious long shot but at any point did any of the aftermarket guys make a 6V71 or similar blower intake for the 331/365/390 Cadillac motors. I have seen these motors in race cars all over the place and even a few supercharged ones but never actually seen the intake itself. I am assuming they are all 4 x 2 toppers as well. That part is available for certain pretty cheap ~250$.

Is this completely unobtainable if it does exist and are there any pictures of such a beast that I could use to make something on the Bridgeport after I CAD it out.

 

Cragar made a 4-71 blower kit for the 49-62 Cadillac engines according to my 1966 Bell catalog. Kit included the manifold which I assume was Cragar.

 

Here's my 331 with a Cragar kit.

 

There you go microbe, maybe you and mercules can hook up. BTW the Cragar kit was only available as vee belt drive .
I can scan the stuff in the catalog and send if you're interested.

 

Ask Ohio George.

 

Someone fabbed one up.....

 

There was one on here in the classifieds about a year or so again,up for $2000.
I wished I had the loot back then,never seen one since for sale.

 

Maybe I can pull the seller up and see if the photos are still available. Still in the planning stages right now, the motor in my 57 is 100% stock right now and at 10:1 compression or so it is not going to survive the blower.

Going out this weekend to look at a 365 from a rear hit car to see if I can swing a buy. Got to figure out what I am going to do for the transmission as well as that sort of power in a 3 ton car is not a recipe for success with a hydromatic.

 

Try Dyer's

 

A 6V71 is different then a 6-71, the blowers shown so far are off straight not the V engines.

 

I have a NOS 471 Caddy Manifold and blower (not for sale) to use on my 32 Fiv'rr with 331 Caddy. If going to Detroit AutoRama in February and want to see it, I will have it on display as a prop with my 32.

 

Actually the picture is exactly what I needed. Someone sent me a diagram of the mounting surface and bolt locations of the blower as well. With that I can mill or 3D print and cast something out pretty cheap if we go that route.
Might just make the upper plate and hack apart a factory manifold for the lower, this is a long term project so I have some time to figure it out properly.

 

Did this ever happen?

 

I have it in solidworks but the casting would be too difficult for me, honestly I have been looking at cutting up a old manifold and seeing if I can just mate a blower upper to it at this point.

 

6V71


6-71

 

I'm interested in a 6-71 or maybe even a 4-71 for the 390.

 

As popular as 331 - 390 Caddy V8's are becoming, it's surprising that there aren't many new, (or repro), intakes available. A new dual quad intake would be cool. A new blower intake would be great. New adjustable rockers would be nice, too.

 

It's only because I decided to build one. If anyone wants something to skyrocket in price, let me know.

 

Would you share the solidworks file?

Who knows, the fins on the manifold are underneath. Developed from a Cragar or Horne multi- carb?

JEM (Jack McAFEE) manifold according to Pat GANAHL in his book. Couldn't locate anything on a 6-71 intake.

 

I m looking for a blower intake as well, for my 365....

 

Hi all,I make a 6-71 to 331-390 CAD blower intake manifold. Cheers,Squeak Bell.

 

Uh oh, this changes everything.

 

Hey there - I'm building a 365 Cadillac and I would like to know if you still have these beautiful blower intake manifolds for them. Thanks much!

 

Well sounds like squeak bell is your answer, man this site is amazing that’s a nice piece of work man

 

Talk about from the dead. I actually ended up going full NA build on the 365 due to my lack of casting ability. i have another block though for my next 28 build and will be contacting Squeak soon to get one ordered up just in case.

 

Also there is a Gear Drive cast blower intake for the Cadillac,,,,,,their in Minnesota I think .
I believe the website is Lakeheaders.com .
I usually type in gear drive speed custom parts,,,or something like that .
If he’s sold out ,,,,he usually cast more in a few months .

Squeak Bell’s is for a 6-71, the Gear Drive is for a 4-71.

 

Yes Sir,,,you’re right .
But I had seen it mentioned in earlier posts for a 4/71 as well,,,,I thought I would put that information on here also .
Never too much info when it comes to obscure , hard to find hot rod parts .
Also,,,,,either one can be adapted for the other size as well,,,,4/71 or 6/71 .
Some of this stuff is very hard to find .
