Hot Rods Was there ever a 4-71 manifold for a 270 Red Ram?

I have been looking for some time. I cannot find a picture of one, let alone one for sale. I am usually pretty good at locating the obscure, if only in images, but I am coming up short.

Does anyone from back in that day remember if they were a thing? I seem to remember seeing a pruned 4-71 on a 241, so that might have been a one-off adapter.

Before I fire up the mill and make a big giant mess, does anyone know if this animal exists?

 

What did Jeff Norwell have on his coupe? I have no idea the blower size or engine size but he may have an answer for you. I do remember it being a baby hemi though.

Edit: Engine is apparently a 270 Red Ram

 

^^^^^me personally do not have an answer for you, except Fire up the mill let the chips fly , hope this customer is willing to pay for flying chips, opposed to the customer a few weeks ago you mentioned they did not want to pay for labor To have a custom part made!!!

 

Nice 5w above its a 3or 4-71, im sure its 4-71

 

@19Eddy30 yep 4-71. If it were a 3-71 would have 2 ribs not 3 on the housing.

 

I see it on there but is it an actual 4-71 manifold, or one someone made?

I can mow the top of of an Offy 2 or 3-deuce manifold and TIG a plate on it, if it comes to that.

 

Ask Norwell (meaning I can't answer the question)

 

@Jeff Norwell can you shine any light on this?

Were these a thing, or are they handmade? If they were a thing, did they make like 15 of them?

My customers want the most difficult things.

 

Thanks on rib info, I was not aware of a 3-71 or seen one ( until i read about a few weeks ago) at least do not recall,
I believe size to a 20-71 .

Guys like you,(Gypsyrods) others & me make a one off parts Too

 

There was a 2-71:


And a 1-71:


I believe that they topped out at the V24-71.

One cylinder set to rule them all!

 

2-71 looks modern,
How about info on1-71 interesting? Tractor ?
& how was it mounted (direct crank end) & inlet .
@ first look it looks just like a bearing plate , but know its not.

 

1-71 is in the back/side, out the bottom, or vice versa.

It was a 15hp stationary engine. Pumps, marine, and generators.

 

I have seen a Red Ram with an actual 4-71 intake not a fabbed one. Seems like the man said it was a Crower. The reason I remember (I usually overlook blower cars at cruises) is that it had the pop off valve, something you don't see a lot.

I got an idea that they are made from unobtainium.

 

Try Matt at lakesheaders.com? He makes Caddy ones... so maybe.......?

 

I am going to shake the tree for an Offy that I can ruin.

 

Just for the record, the 241 and 270 use the same block and heads. There's also a 315 on the same block. I've only seen a 315 in trucks.

 

My understanding is that the 315 came in big trucks. I have seen them in small dump trucks. 2x4 motors.

 

It would appear that his is fabricated.

 

Yup they did, two 12V71 blocks bolted together, worked on a couple about 20 years ago. They were the prime movers for generators in a waste plant in Pacifica CA. The sound was unbelievable! Makes me smile juste remembering them.

 

Just copied this from an article about Norwell's coupe.
Karl Spafford of TDC built an evil 270ci (bored) 1955 Dodge Red Ram Hemi. With the block machined, he filled it with a steel crank linked to matching rods capped with Ross Racing forged aluminum pistons getting bumped by a Clay Smith stick. Hopped-up stock heads meet a Don Hampton intake with a GMC 4-71 blower topped by twin Rochester 2GC carbs and Stelling & Hellings-style air cleaners. A reworked GM T5 trans matched to a Wilcap adapter meets a custom driveshaft.

 

I never seen one and have been looking for 30 years. I talked to a lot of races that were using the redram and all had fabricated intakes. I talked to a guy who worked at Dyers and he said he never see a production one only fab sheet metal ones.
I got a extra 3x2 intake I will mill down and make one. Also a 6x2 if I want to get Exotic……. And put the 471 on top of that.
I thought the 315 was a tall deck and picked up a 3x2 for one of them forgetting about the tall and low deck hemis.

 

@Jeff Norwell thanks for the information and just sent Hampton a email.
Your redram is wicked cool .. do you have any detail pictures of the motor. Thank you

 

@Jeff Norwell builds the dreamiest cars!

 

How dare you use cowl steering! Don't ya know you'll die!!!!!!!???????

 

I am looking for a blueprint for the 241/270 right now to see about making a fixture to hold the intake in the mill.

I have access to a 5-axis CNC, and could likely make a replica of the attachment surfaces on the heads that the manifold attaches to, that could be bolted into the mill and indexed.

First and foremost, I need to see if the customer is up for paying!
