Edelbrock Scorpion & Tarantula Manifolds

Recently ran across these intakes at a swap meet. Never used them back in the 70s, had a Victor Jr. What were these used for and what were they effective on? The Scorpion had a breather tube between the carb and distributor, was that original? Thanks.

Those were the go to manifolds in the 70s.

I had a square port Tarantula on a 427 in the early 80s.
Ran 11.60s in '67 Camaro, street legal car w/mufflers, 3250#, 10.5W tire, 4.88 rear, TH400 w/3500 stall, hydraulic cam, 750 Holley

Saw a lot of Scorpions on SBC back then.

I seem to remember seeing the breather tubes blocked with a freeze plug on some intakes that had that.
They pre-dated the Victor series stuff.

That was a long time ago...

In 1972, most guys with SBC's started with an out of the box TM1 (Tarantula)
That is unless your name was Lingenfelter ;-)
The Torker that followed worked on some small inch auto combos. Never worked any better for me ,with a stick car.

So the TM 1 is a Tarnatula? I remember seeing a manifold with the spider cast in the front. I also saw the TM 1 manifold. Both of these manifolds seem to have less plenum volume than the newer intakes, what was the intended application? High rpm? Would they work with engines running 5000 to 5500 rpm?

For a street car, yes.

Had a TM1 on my 56 150, 327/365HP. Ran great once you got past 4500 RPM’s. The only thing that saved this combo for the street was the addition of a Skip Asay plenum divider. And had I taken the magazine article seriously about securing the bottom of the plenum divider plate so that it wouldn’t vibrate, the retaining ear of the plate wouldn’t have broken off and taken out a cylinder!
