Ongoing Victor vs. Performer manifolds

A while ago, I asked advise on this very forum on a Edelbrock Performer manifold compared to a Victor. The advise I was given was to use the dual-plane Performer because it should make more mid-range power and give up very little top-end power.

Here are the dyno results. Ready? Sure? Ok...

The Performer not only produced 30 less HP on the top end, it produced 50 (yes that's 5-0, not 1-5) less ft/lbs. maximum torque.

And it was not any more streetable.

For bigger FE's with ported heads, big valves, greater than 240-degree timing and greater than .600" lift, it seems that from a sample of one, the Victor is the manifold of choice.

Remember, this is a sample of one, but I thought it might be interesting for those on the fence. Plus, it LOOKS like a REAL motor.

What do you mean it looks like a real motor? Is it painted orange?

before my webers I ran a Victor and a 750 Deamon carb, it ran fantastic and it does look good, although not period.

On my 351W I dynoed my favored dual plane 6500rpm peak rated Stealth with 3/4" carb spacer vs a V-jr. The dyno tests were one year apart, same shop. The motor peaks torque 5000(stealth)-5200rpm(V-Jr) and is done at 6200rpm. The V-Jr walked away everywhere above 4300rpm with a steady 15-20 rise in both curves. I sold the Stealth.
