Thread: Edelbrock Streetmaster

Tweet

I've been looking around at different intakes for my Bel air, and I stumbled across an Edelbrock Streetmaster intake on eBay. I see it has a raised floor unlike the flat floor in the Torker II on my Chevy. Also it looks like the ports are a little smaller, I'm guessing to help lower end torque? How would one of these compare to a Torker? I'm probably not going to get one, just curious.

Old technology. I am not a fan of single plane intakes on street cars. You will not see any benefit from them until at least 4000 rpm where you spend maybe 5% of your driving time. If you must have a single plane intake, Victor Jr. will out perform it. A good dual plane intake like the Performer RPM or Weiand Stealth would be a much better choice, IMO.

Concur w/Lynn - Performer RPM is good all around street manifold. I like it with a Q-Jet, but have used it with 600-750CFM Edelbrocks too..

I'm planning on getting a dual plane, just wondering about the differences

There were two versions of the Streetmaster one looked like the old style Torker I the second like the Torker II,the #I had straight runners and a square bore flange the #2 had curved runners and a Carb flange is like a 2101 Performer,These both came out around the time of the Jimmy Carter "gas crisis" the small runners were to improve port velocity at lower speeds to promote better mileage and they worked well.They may be a single plane but the RPM range was off idle to 5,000 Max,several cam grinders offered RV & mileage cams Holley had a Economaster that was 450 CFM to replace Quadrajets and the Carb of choice for the square bore intake was the 500 CFM Carter.I was working at M&M Speed and sold a lot of those we even built a "mule motor " for my '65 El Camino it was a 283 bored .060 mild porting with the #1 Intake and a Crower mileage Cam and it could get 26 MPG pulling the grade to Tahoe up U.S. 50 and still run a high 14 second ET at Sacramento Raceway with it's Muncie 4 speed and 3:73's.streetmaster sbc.jpgscan0043 M&M.jpgjun16intakes16.jpg Another Intake that was popular in the same era was the Offenhauser Dual-Port 360.

Some great pictures Jeff! Thanks for the little trip down "memory lane"..

If your car is used primarily in town and for highway cruising the Streetmaster will do you good with stock heads and a moderate camshaft,I would use it before the 2101 Performer intake which you can find on craigslist and ebay for $40-$60 all day long.

I agree. I used a Streetmaster on a 302 Ford and the throttle response was fantastic, idle to 4500. I have never recommended the 2101 because I see it as a lightweight stock intake manifold, whose only advantage over a stock cast iron manifold is the weight reduction off the front end. In my opinion, the best street intake is the Edelbrock Performer RPM. Makes more power from 1500 to 6500 than any other manifold I have used. Again, just my opinion, but I think the RPM with a Quadrajet is just about the best combo that you can bolt onto a street motor.

Large runner, single plane intakes work well on roundy-round cars that need to make power from 4500 to 8500 or a drag motor with high-stall converter. I wouldn't be seduced into using an Air Gap RPM if the weather in your area is a little on the cool side.
