Kind of curious now, why whould someone use a P7100 pump instead of the P3000?
The P3000 cant push enough fuel?
EDIT: Now i see you just posted....
I cannot say how they compare directly, we use them on our diamond drills and only use them with the p-pump. Our only VE pumped engines are a B3.3 and a pair of 6BTAA's on totally different drills.
The p3000 does not have electronic timing, at least none of ours do, oil lubd like the p7100. full mechanical engine, give it fuel and spin it over and its good to go!
I can say though, our P3000 pumped 3.9s seem to always have a mysterious 'surge' at higher RPMs under light/no load which is pretty hard on the engine mounts. Not sure exactly what the cause is, even cummins is stumped...
