Ive got a edelbrock streetmaster intake in my 56 chevy with a 327 but I can't find any info on what the manifold was designed for and when it was made......anybody have the details on this??? thanks
Meatball, they are a single plane intake, BUT with small ports so it doesn't affect low end torque like a normal single plane. I have one I'm going to use on my 318. As far as I can tell they were brought out in the 70's sometime, early to mid? hope this helps. later shawn
I've run this manifold on my roadster since 1978, purchased it from Midwest Auto Parts in Cleveland. The only difference I can see is the floor of the plenuem is raised instead of flat like the Tarantula manifold. It is a very responive manifold....fuel doesn't puddle on floor of the manifold. Hope this helps; also I running a 650 cfm single squirter Holley carb.
I think that they were sold in the mid/late 70's as roadster 1923 said he bought his. And I think that what he said about it being quite similar to the Tarantula but intended to be streetable is correct. If you dig out some late 70s Hotrod, Car Craft or Popular Hot Rodding you will probably find the adds for them and maybe an article on them. <input id="gwProxy" type="hidden"><!--Session data--><input onclick="jsCall();" id="jsProxy" type="hidden">
Thanks.yeah its seems to respond very well Im running a Edelbrock 1404 and it works well as a pair I just didnt remember the manifold and like how it works,seems about right as the car was built in the mid 70s
MEATBALL...edelbrock has a internet site, just type in edelbrock. or contact JEG's by phone and ask for tech. dept. but i do know it's a duel plain manifold for street driving. good luck with your search...POP.
Somebody mentioned buying one in 78, had to be in the final years of production. Good luck finding info at jegs or on edelbrock's site! What are you wanting to know? Would tech info make you change your mind about using it? If it works good you may have a case of ignorance is bliss.
NO its been on the car since the 70s but I just wondered what it was setup for ie bottom end etc. its works better than the torker I had on my 39 I think...I just dont remember the name and wondered about when they made them,Im making sure most of this car stays period mid 70s.......and I couldnt find anything online about it,so I went to the experts
I think they was supposed to be for power and fuel efficiency on a stock type motor . Small runners for single plane and look at the turns in the ports, they are ribbed for fuel/air mixture . Seem to work good on stock or mild cam motors like intended . I picked one up for my FE , used them on SBC before
OK,time for an "Ol Fart" to weigh in Back in the day I sold a lot of these intakes in the 70's,there were two reasons they became popular.After 1970 the emission phase came along and horsepower went way down and gas mileage too. and we also had the so called Jimmy Carter "gas crisis".Edelbrock came out with the Streetmaster and Offenhauser brought out the Dual Port,the idea was to increase fuel mileage and low end torque by increasing flow velocity by using smaller runners.For the SBC guys there were two versions of the Streetmaster the first had runners like the original Torker "X" shape and was for Holley & AFB square bore carbs,the second version had curved runners like a Torker II but had a multi-fit flange like a Performer so it would accept Quadrajets or Holleys Economaster Carb.We built a motor in our shop that was put in my '65 El Camino which had a Muncie 4 speed and a 3:73 12 bolt using version 1 intake and a 9400 Carter AFB and a Crower RV/Mileage cam (still available) and headers and some ignition mods.It would average 26 MPG going up the inclines from Sacramento to Lake Tahoe up Hwy 50 and still run 15.40 ET's at Sacramento Raceway.Peak RPM would fall off at around 5,000 with this setup.We tried the version 2 intake with the same Carb and RPM's fell off at around 4500 and felt an overall power loss.The Edelbrock rep gave us info to work with when we did the build these intakes work well with cams that have a smaller split duration and a smaller CFM Carb,version 1 if used with a Carb spacer can produce more RPM.The Streetmasters for other engines are somewhat different in tuning them as compared to the SBC.
thanks Jeff yeah that sounds right I havent had it much over five grand but I am happy with the way it works,thats kinda why I wanted some background on it,,,,,,,,I still gotta play with the tune on the motor but I think this answers some questions .thanks guys..........
Real good street intake . They were very popular back in the 70's . I haven't seen one of them for a good while . RetroJim
This must be version two because it was for a spreadbore, it had good response with a Holley 650 dp spreadbore on it before I went with the tow fours.
I ran the 302 Ford version in my roadster for a long time. Not sure it was really an optimized setup, but ran well enough for over a hudred thousand miles.
Well, I'm glad to know that I'm not the only one that has one. Actually, from what I've read here, my application is just about what the intake was made for (a pure accident, of course). It's a stock 283, with a small Edelbrock carb (500 cfm). I really ended up with the thing because it was in good shape, had the front oil tube hole & only $40. I only recently started & ran my (unrebuilt) motor, but everything seems O.K. (knock on my wooden head). Very interesting info...thanks.
Around the same time there was also the S.P.2.P. Intake, they were a P.O.S. no good for power and excessive lean problems,not even a good garage decoration.
You are running the same Torker style manifold that I have on my roadster, not the later version. I'm also running an HEI with a curve kit. I have never had any concerns with the manifold. Steve
I picked one up lately from a guy who used to run it on a 350 with a 151 cam in a 64 imp. he said it ran great(don't remember his carb choice...). I would like to run it in my 55 s-box with a 200-4r, on a 327 or 350 with edelbrock 6073 rpm's( Painted to match the black block). i am even considering running my (port matched and bowl blended)1.84 valved 041's if some of you guys older than me fill me in on the finer things involved with respect to this combo.
By pure coincidince the henry j I just got has the first version on it, but the oil fill tube is not drilled.
Mine is just like yours... straight runners and no fill tube hole drilled...yet. do you have lots of run time with this car's combo? engine size? build purpose?
No I just bought it a couple weeks ago, drove it around the pits a bit, it has a vac***e leak somewhere. To be honest I plan on changing the top half of the engine plus cam before it hits the road so I'm not worrying about it.
Awhile back I googled streetmaster 3225 and found a site that was pretty informative ( I didn't save the site). Found out the chevy one I have is the second version as it has 3 or 4 vertical rods, for lack of a better word, cast in the area between the plenuim and runners. Am putting a mild 327 or 283 with a 700R4 in my Model A tudor, would this be a good choice? Also have a Carter 625cfm carb from the '70's I was thinking of using.
Back when the Streetmaster was introduced much of the testing was done with the Carter Compe***ion Series carbs at Edelbrock,for a 327 or 350 your 625CFM Carter should work well in stock form with this intake.The key is selecting a cam that will work with it so low end torque and midrange is what you will want with this intake,my suggestion is this from www.summitracing.com put this number in search : HRS-111221-10.If you go 283-305-307 a 500CFM would be a better choice.
I am currently running an edelbrock eps intake on a 327(flat tops), chevy 041's with portmatch/bowl blend, with the 204/214@.050 edelbrock cam with headers(full length) through 2.25" pipes(no x-overs) in front of a 700r4, and 3.08 gears in a 3400 lb 81 monte...(more of an experiment than anything...) and WOW! I go for rips that generally burn up four/five tanks of gas at an average speed of 110km/hr(they are more like 70-80mph for short bursts... for p***ing and stuff)... and while cruising at little or no load, the car can fetch 22-24 mpg(candian gallon) with just a driveway tune. In a light car like yours, you will have a lot of fun and a very economical cruise range and an absolute blast when/if you like the 40-80mph cruise zone. My o/d has a bootstrap eliminator kit installed and runs the lockup circuit hydraulically... flat out cruising without coming out of o/d at .75 throttle opening,(hehehehehe)... have fun with that ride however you finish it up!
Oh yeah... also forgot to add that i must cross several mountain ranges and the tallest one is 1740m above sea level( idk,4300'??) and i start at sea level. Mine runs a 600 cfm performer carb and might be a little on the rich side at times but just the same, not a hiccup out of that setup... maybe a richer jetted 500 could help increase mpg... but that would be the only thing i would change. The mallory ignition took a dump on me at 33000 miles, and the msd i replaced it with runs fantastic right out of the box. hope this helps... opinions are like belly ****ons and everybody has one...
Jeffb2 and Sooper thanks for info is very helpful. Have always just used crate motors in the past but want to put one togrther for this car as I have quite a lot few parts to chose from. Also forgot to say in first post, the car will have a nine inch with 3:73 gears. Bjinx
