There's a ton of misinformation out there on 215 pumps. They run well, and when setup by a good pump builder, they can flow a lot of fuel. It's a long injection window to inject all 600+ cc's, but that's nothing some more injection base timing can't help!!!
The plungers have a notch, when in the notch, timing is reduced a few degrees, when rotated beyond the notch, timing comes right back up to baseline so no "retard" at full throttle. When setup perfect by a great pump shop, your baseline timing can be in the retarded part of the notch and then as you give it more throttle (rack travel) it can rotate up the helix to the advanced position. That's right, timing can advance a few degrees with the throttle application!!!
FYI, there's quite a bit of difference in total fuel flow capacity:
The upper limit of most built 180 pumps is 500 cc's
The upper limit of most built 215 pumps is 650 cc's.
