My 318 is stock other than the intake, headers, and the Summit 6901 cam, and only makes power to 4950 RPM. It can't even get to where the HP and TQ curves cross at 5252! With the low compression and crappy 318 heads, it probably won't no matter what I do.
Yes all very interesting. Considering that Chrysler supplied single plane intakes on 273s, I'm not convince the short runners and combined plenum are always a loss at street rpms and low throttle. Keep us posted. This will be awsome.
