Edelbrock Streetmaster 318

[Darter6]

The only real difference is the port size is smaller than a 360.
You could gasket match. Or if the 360 is basic and stock you might never notice a difference.

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'.

I have a book written by Paul Zazarine on the Pontiac GTO. He was a large man & I believe he passed way. Same bloke?

Sadly Paul Zazarine died at the age of 58 in 2011.
69 Cúda 440 has posted well past that date.

saw one of these on fb marketplace for $150 could stop from wondering whither it would work on a 360?

I would only use the Edelbrock Streetmaster on a mileage seeking adventure. Or the SP2 intake.

You’re better off with a Weiand Action Plus or a RPM.

Same bolt up, smaller passages and plenum restrictor, great from idle to 4500

Bolt up, yes. Work well on a 360, I wouldn't myself. They are designed for 318's with small ports and a restricted plenum under the carb flange. A Weiand Stealth or a newer Edelbrock Performer would work better I think. A old LD 340 would work well on a 360 as well. THey are still around but are a bit hard to find and spendy. Can you say "restrictor plate"?

Definitely for mpg, and less weight, no egr, it would be in the motor home
