Manifold pro & cons

N&S. No pro-s or con-s to the Torker, as its a very good manifold and Edelbrock has very good quality. Its the "works best with" RPM range that's different. The Torker is best suited for mid-upper rpm ranges, where a dual plane Performer "works best" at the lower rpm ranges. (Plus I'm thinking, and could be wrong here, that the Torker will raise the overall height so you will have an issue with your cover).

I have a Torker with a Holley 600cfm with 2 gaskets and and it does raise the cover a bit, approx 1/8". I installed a new 770cfm and the choke linkage hit the manifold when the throttle was opened past half way. I ground down the portion to clear. So be careful your throttle could stick open. I have put the 600 back on, it seemed that the 770 was a bit too large for a stock 351c. I'll save it for the rebuild or mess with the jets.

Curt, You say only about a 1/8". I had to put some small spacers on my cover when I went with a aftermarket chrome air cleaner because it sat a little higher. I would hate to see it go any higher as it would be noticable then.
Your thoughts??

tom.... one option you have, would be to (if you go with the torker) is to run a lower airfilter element. I ended up measuring the max I could fit under the engine cover, took the good ol' tape
measure to the local autozone and found one that just fits.

So you've decided on that unit versus a Performer style?

As said above, the Torker (miss-named) is better
on the high end, while the Performer is better on the low end. There was a comparison test long ago that showed that these two manifolds were better than the rest. (This did not include the new crop of "high rise" manifolds like the "Funnelweb" or PI's 3V (I think that is the name).

I know of a (used) Torker for sale...

I can buy a used one for a good price. I have been looking for a used Performer, but have not been able to come across one so far.

Have you seen the solution from down under? Parker's airgap high rise manifold setup for both carb or Fuel Injected. I just had it Jet Hot coated and setup for Fuel Injection...SWEET

The Edelbrock Torker is an open plenum intake while the Performer is a dual-plane type. Typically, open plenum units are high-rpm racing types while dual planes are more allied to street use. Dyno tests have shown that a typical engine gets more midrange power & torque from the Performer than from the Torker, and on most engines the peak power is virtually the same. It gets complicated a little in that original '70s-version Torkers were big-port 4V types but later, there was a 'Torker-2' that fit small port 2V heads, and guys found by accident that adding the small port intake to the big-port heads allowed all of the benefits of anti-reversion plates with no extra parts (these plates add huge amounts of mid-range torque & street driveability to most engines). The downside of the large mismatch in port size is, around 5500 rpms the mismatched intake falls flat on its face, but if your engine doesn't spend much time in those regions, this is an excellent choice as well.
