Did you need a different oil pickup from the 2wd or did the 4wd version fit? I have a 4.3 out of an 89 Blazer and the oil pan is way too low. I have been looking for an alternative with no luck.More swap info:
The oil pan: my engine came out of a 92' 4wd trailblazer. The oil pan hangs ridiculously low, so it was swapped to the 2wd oil pan which saves about 3" but then you have to modify the dipstick, they have discontinued the part for a replacement.
