Best Intake for a 522BBC
I'm rebuilding my motor and I switched the heads to the AFR 305's and need a new intake. I was running the Iron Merlin 270's with a Brodix HX. My cam is a hydraulic roller .624/.612 lift and 242/252 @ .050" duration. With about 10:1 compression, my peak power should be about 5500rpm. The carb is a Pro Systems 4150 940cfm. What does everyone recommend for an intake? I'm leaning towards an Edelbrock 454 R, or World Products marine version.

454R made 20 more hp than the dart on my 502s with 305 cc afr heads. I ended up making 605 with similar setup, 454 R and holley 950 race carb.

How is the low end with the 454R? I am trying to maximize my average HP from 2000-6000rpm to get the best overall performance. How do the torque curves compare? A couple of racers I've talked to really like the Brodix HV for overall power.

I would have thought that this topic would have created a veritable firestorm of debate.
