I'm running a moderately aggressive street-driven 351C in a 1970 SportsRoof. (Deails in My Garage) What do you think: Will I see significantly faster acceleration (2500 RPM to 6500 RPM) with the new Edelbrock 351C Performer RPM Airgap intake instead of the current Weiand X-celerator intake? DynoSim indicates that a "dual-plane max-flow" manifold will produce more total power under the torque curve than a "single-plane max-flow" manifold, but I don't have any info on the Performer RPM Airgap manifold. Thanks!
