: Edelbrock intake info

I have a single plane Edelbrock intake on the BBC that was on it when I got the car. It is a Torker 2-0, but does not look anything like the Torker 2-0 you can buy today. It is a taller intake and it has a twisted plume. The carb does not sit on the intake straight, instead it is pointed about 30 degrees to the passenger side. Can anyone tell me anything about this? Is it junk since they redesigned it?

Thanks

That's an older intake but works fairly well, many people have made good power with it over the years. The only design flaw is where the intake runners meet the head ports there is an abrupt angle not seen in the newer designs. I'm sure an RPM airgap would make more power all the way up to 6500 rpms.

I am beginning to rebuild my 454 for street/strip duty. I have been torn between the Edelbrock Air Gap and this Weiand Stealth. I thought I read on this forum at one time that the Stealth outperforms the Air Gap. Does anyone have any more info on these two manifolds?

The Torker that you have was the hot set up back in the 70's. The twisted design allowed for more equal length runners.

What about in the 90's? Is it an outdated design in comparison with the Air Gap and Stealth performance numbers?

The main difference between the older style "sideways" torker is it's a single plane and RPM and Stealth are dual planes.
There won't be much difference between the RPM/Stealth seeing as their both dual planes.

If we still had 96 -98 Octane pump gas available on every corner, items like the old style Torker that you are describing and the real big cams and compression that went with them would not be an issue. But the fact is, we now run 92 - 94 octane, and with the lower compression comes shorter duration cams with steeper ramps and other items like dual plane intakes. Back in the heyday of the twisted Torker, 10/1 CR was for a grocery getter. A run of the mill performance motor was 11/1 and at 12.5 you were starting to get serious about street/strip performance. Times change.

The 70's were the hey day of the single plain street intakes.Like GRN69CHV said , the engines and gasoline were entirely different back then.... No one had the fast acting cams like todays stuff..so compression had to be higher... 3.73's were considered " Freeway " gears...4.88's on street cars was fairly common.... Back then a 244 deg @ .050 hyd cam generally had a 310 deg advertised duration... Today it's 292 and sometimes even less.

Anyhoo the old Torker with the twisted plenum was there due to the large cylinder head offset that the BBC had.... Back then they really hadnt figured out how to make a single plain work well.... lots of changes were going on back then..
In fact it was Holley on their " Strip Dominator " for the BBC that really showed some promise with respect to runner configuration.... but inside the plenum Holley didnt do as well with their sharp edges thay had on those intakes....

Anyhoo the 1st gen Torkers were VERY POPULAR back then as they worked superisingly well vs the dual plains that were around back then..... ( With the Compression and long cam timing and low gearing ) that everyone ran back then....

But the newer Dual Plains of today have alot more research and engenerring than the old style ones of decades ago....Thats not to say an old Torker wont work well.... it certinally can but with todays engine combos there isnt much need for a single plane Torker unless you are running a 2bbl or a big inch motor and have too much torque anyways..... But for a typical of todays 6500 RPM " Street " cars a dual plane works great.
