Boeing started firm configuration of the 7J7 in 1985, probably shortly after the 737-300 entered service. Already having a brand-new model entering service, they looked to what they felt were viable technologies within the next decade including FBW, glass-cockpits, lithium-aluminum alloys, CFRP and new engine technologies (UDF) offering significant fuel efficiencies as fuel prices had doubled between 1978 and 1981. That they would return to 1978 prices by 1988 and the failure of the first generation UDFs to meet noise and vibration targets led to the engine falling out of failure and Boeing also investigated using the SuperFan engine being developed for the A340 in a traditional under-wing installation.
And let us not forget that Airbus had second-mover advantage - they knew what Boeing was planning with the 737-300 as well as having seen how airlines were using the 757-200. So they could tailor the A320 to provide more capacity than the 737-300 with similar design range to what most operators at the time were doing with the 757-200 (even if the 757-200 could go farther).

Not really considering the 7J7 was designed to replace the 727-200 as a short-to-medium range airliner whereas MoM is designed to replace the 767-200ER (and A310) as a medium-to-long range airliner.

It is unfortunate that PDX Lite is no longer updating the A320no and 737MAX sales charts as I would not be surprised if the MAX's sales surge since the launch of the 737-10 (beyond just the model conversions from existing orders) has probably significantly shrunk the respective "sales per day" metric between the two. And considering the MAX has been on offer for less time, I don't think Boeing is at risk of having anything less than a serious NB presence.
