Old Edelbrock Tarantula Intake Any Good?

Hot Rod did a test last year on a 383 using a bunch of different manifolds and the RPM Air Gap outperformed an old Edelbrock single plane by a mile. I don't remember the exact numbers, but the bottom line is that for the street, you can't beat the RPM Air Gap.

Well 2 things come to mind, 1 did they change the jetting of the carbs since a dual plane intake should take smaller-but not always-jets than a single plane intake. Also it can usually take a smaller CFM carb to make best power-but my TM 5 papers saids for strip use, use a 850 dp-thats what it says.

And 2nd, the RPM air gap is for sale NOW, why in the world would a Mag. post something that would hurt their ad business ? Edelbrock spends big bucks every month running ads in Hot Rod Mag, kind of makes Hot Rod biased.

If you look at Edelbrock cams, the Torker 2 cam has LESS duration than the RPM intake cam. Which makes sense, the dual plane will make better power at lower RPM's so the cam could be bigger and this way the motor will still pull good at 6500. The Torker 2 cam needs less duration since the intake is tuned for higher RPM's.

So to really compare intakes, you need to change the cams as well.

I will say the RPM intake is a great-"can't go too far wrong intake" and it will work great in more cars than a Torker intake would.
