Just curious which is the superior intake and how close they are performance wise. Edelbrock Performer or CH4B. From a very old big block manifold shootout, what I recall is they're very close, almost indistinguishable, performance wise.

If I had to guess buy and sue one it would be the RPM   I would say it depends on the application and usage.  The standard Performer is rated at idle to 5500, While the Performer RPM is 1500 to 6500. The CH4B maybe in the middle. lot's of info on Google

https://www.motortrend.com/how-to/mopp-0207-intake-manifold-engine-and-rpm-range-test/Per the above, the Performer RPM is a bit better overall than the CH4B. However, if hood clearance is an issue, the CH4B is closer to OEM height.

I tested the 68 440 mani, the CH4B and the TM7 at the track in 74 on a 426 street wedge with a small cam and 11" converter. The stock mani 13.37 the CH4B 13.34 and the TM7 12.98. This car was very repeatable within a couple of hundredths and I bracket raced it while I was building a new engine for my main race car.

If I had to guess buy and sue one it would be the RPM please don't "sue" the intake Cab.........  [just kidding !] i think the RPM intake [both versions] may be the best bang for the buck, considering the CH4B seems to be getting a little hard to come by at times. of course, having both intakes, i haven't looked for a while.

Of the Original Poster has a stock 440 with smaller than the factory HP 375 HP cam specs: 268/284 Duration, 0.450"/0.458" lift, 46 degrees overlap (115 LSA), installed at 113 Intake CL. And street gears like 3.23 or smaller.... the smaller Performer should be fine. Even with that stock 383/440 HP cam the Performer RPM might be an improvement over the Performer.
