Below is an old but interesting article on the "dog-fights" in Test matches between Pakistan and West Indies from 1976-91 (time-frame beginning after Australian rout of Windies in 75-76) during which time West Indies totally dominated every team - home and abroad - losing just one Test series.
While the mighty Windies in late 70s and throughout 80s were crushing all and sundry, losing just that single test series in New Zealand, Imran's team seems to be the only one that really stood up to them consistently during these 15 years.
Imran's team drew the series against the Windies at home in 85-86 and again away in the West Indies in 88-89, and then again at home in 90-91.
Most impressive is the fact that it was the only team to win a test match, and draw a series against West Indies in the West Indies in the entire decade of 80s (really should have won that series in 88-89 if it were not for some horrendous umpiring when the Windies, tottering at 180-7, finally won the match by reaching the required total at 268-8).
Several of the matches between the two sides were truly dog-fights, especially in the 80s.
With both teams having great bowlers, innings totals for both teams rarely exceeded 400 runs (less than 300 runs in most cases). And Viv Richards was the only batsman - from both sides - to average greater than 50 in multiple series.
During this same time from mid-70s to early 90s West Indies were bullying every team in the world with their fast bowlers - especially at home - but their record against Pakistan was pretty even 6-4 (with 8 draws) and 3-3 after Wasim Akram made his debut.
West Indies win-loss record against major teams during the same time for comparison.:
Australia: (31 played) = 17 wins - 5 losses
England: (38 played) = 24 wins - 3 losses
India: (29 played) = 11 wins - 3 losses
Pakistan (18 played) = 6 wins - 4 losses
