I have a 4910 and 501 ported the same, they’re always identical in timed cuts. I think more guys build the 4910 because they’re cheaper. Timing curve could be different, but I saw no gains from swapping!Have no links saved, but any 4910 I see seems to be faster than the 501P,
so if they have the same engine it might be the ignition module / timing that is helping them out, same with the ported 4910 I see on the tube, they run better than any 501P I have seen.
