Find an Edelbrock street Ram. Don't see em advertiesed but mine runs great right off the bottom. Excellent throttle response. Check out this months Super Chevy, they do a tunnel ram comparo. Because of equal runners and proper cross section design, the ram pulls better over a wider range of RPM than a Victor.
383, 11.6:1, 226/489 at .050, aluminum vett fulies, 2x500CFM Edelbrock carbs with tiny Q-Jet style primaries. The key is the high compression and tiny primaries. I will state the engine is under cammed and the heads are just not up to the task. Soon to be remedied.
