Reply to "Single plane or dual plane?"

throttledMember

I am running a 408W with a bit more compression at 11:1 with the same RHS 215 heads. My cam is 236/248 duration and I made the switch from the RPM air Gap dual plane to a (ported) Victor Jr. single plane. If I lost anything on the low end, the seat of the pants dyno didn't notice but I did notice a pick up in the upper revs and wouldn't go back. Hope that helps!
