Edelbrock Streetmaster

Designed by Edelbrock, and first released in 1973.

First designed for the Small Block Chevrolet {350/160 HP} that
was found in the Chevrolet K5 Blazer.

* Profile > Single-Plane Low-Rise Intake
* Style > Short-length runners with narrow passages

Edlelbrock Engineers {Research and Development} came up with this Manifold, primarily to help fuel mileage and efficiency for small block engines.

The goal >
* To provide for better vehicle responsiveness on the low-end.
* To allow for a more uniform fuel distribution.
* Better cylinder filling.
* Reduce emissions at lower RPM's.
* Increase fuel mileage.

The small runners increased velocity at low Rpm's, which helped improve efficiency.

There was better fuel atomization which helped fill the cylinders
quicker.

Edelbrock announced that this Manifold improved fuel mileage by
9% to 14% in economy driving.

It was accurately marketed, as a 'Mileage/Performance' Intake Manifold, that improved economy for daily driving habits.

Marketed for >
* Daily Drivers
* Motor Homes
* Pick-Up Trucks
* Campers
* Vans
* Station Wagons

A true 'Off-Idle to Cruising-RPM' Intake Manifold.

Awarded the 'Best New Product' at the 1973 SEMA Trade Show

I have one and wondered if it would be good for a mild 10-15 lb 318 turbo build I might do.

Any thoughts on that fellas.

The Edelbrock Streetmaster #3275 is a decent functional Intake Manifold for a
mild 318.

Primarily designed for > Off-Idle to 4500 RPM's.

Once you get above 4500 RPM's, it does fall flat though.
 
Yes, I talked my son out of it and into a Torker I have for his hot rod 318.

It's just one I've got and wondered if the pressure would over come that as the only other ones I have are an SP2P or Holley Strip Dominator in aluminum.

Just wonderin' out loud.

I bought the Weiand Action Plus. Gobs of low end, as it is designed for off idle, and will pull to 6 grand with a mild cam and headers, especially if its feeding the likes of a 2.02 x head. Will accept spread bore or square bore, and that's a big ++++! Advertised, though, to make power from idle - 5500.

Pressure on the engine? Go with the single plane Torker or Strip Dom. No doubt, ether one.
 
Looking at that streetmaster, it kinda gives the impression of the early 273 2 bbl single plane.(Chrysler musta been up to something)I have no comment either way, but always thought that a dual plane was better for bottom and mid range. That statement is kinda of a question. Any thoughts ?

Scat-Pack-North

Before you change Intakes.

What Carburetor are you running with now ?

Paul
 
I would just leave the ld4b on it, its a pretty good intake for your combo.

LD4B!!!! :burnout:
 
I have one of these intakes, been trying to find a 500cfm 4 barrel to run it on my 273 daily driver. Throttle blades on a 600 won't clear unless I run a spacer which I am afraid will affect the purpose and design of the intake.

Exactly,

The smaller sized 'plenum' on the 'Streetmaster 318' is designed for that purpose,
a smaller CFM-rated Carburetor.

The early Carter AFB's {Advertised @ 500 CFMs'} off the 273 Commando have.
* Primary ....... 1 7/16" {1.437"}
* Secondary ... 1 9/16" {1.562"}

A too big Carburetor on the 'Streetmaster 318' defeats the intent {purpose} of the
low-rise single-plane Manifold.

I have used an older Holley 550 CFM {1 9/16" x 1 9/16" Throttle-Bores} with the
'Streetmaster 318', and it works like 'A Charm'.

Hi Cuda, I was asking a question recently on this forum, regarding a good 4 bl intake for a '69 Dart 273. I don't have many options I've found, however, I did run into the StreetMaster 318 intake for sale online. I have a Holley Street Warrior 600 cfm Square Bore carburetor. You seem to know a lot about Mopars, does this sound like a good match for my engine? The engine is stock but I wanted to add a 4 bl since I was having issues with my 2bl carb and didn't want to put money into a 2 bl set up. Glenn

Just machine the intake like we do with the 273 intakes so we can use a late model Edelbrock.

As Mike said 69 Cuda 440 has passed away. His real name was Paul Caesarine(or something like that)
He knew a lot of drag racing stuff. Do a Google search as well on him.
RIP Paul

I have a book written by Paul Zazarine on the Pontiac GTO. He was a large man & I believe he passed way. Same bloke?
 
You wouldn't use a turbo with a SM intake if you have a choice. The turbo is trying to squeeze more air into the engine, & the small runners on the SM are a hindrance to flow. Counterproductive.
The intake should be matched to the needs of the engine/owner. You do not put a 4500 rpm intake on an engine built to rev to 6000 rpm; etc.
 
As of lately if we were to believe everything we read we would all be putting #302 casting heads on our engines and running Street Masters. You don't see them on drag cars for a reason and you don't see him on any cars anymore for an even better reason.... they sucked outside of 4,000 RPM . They may be an improvement when bolted onto a stock engine but that's it and very limited amount of improvement to my knowledge
