Those exhaust numbers can't be correct are they? Those are as high as a typical intake runner at that level. Did Jim split the intake and exhaust numbers by mistake, when really, those are all intake numbers?

Mike knew I misprinted but wanted to make note of it and have a little fun at the same time.
I noticed the promaxx 340 cnc head which probably has same exh port as the 317's flow like 300 @ 700 so I'd say very similar although the same 340 cnc head intake flows 398 at same lift. I'd like to see 315 @ .700. I recall Jim not real pleased with the out of the box exhaust numbers. If he can work his magic on those as he did the intakes will be a big thumbs up. At the very least more options regarding aftermarket.
