I had a '87 2.8 S-10 automatic and a '90 S-10 4.3 automatic, both were good trucks but no comparison to my '96 Tahoe fullsize 2-dr 4WD 'sport' automatic.
The '87 got about 20 mpg, the '90 18, and 15.5-16.0 is the best my 4WD Tahoe ever gets. But the ride, size, towing capacity and off-road service are first rate. I love the huge engine bay and well laid out chassis. Doesn't feel as "cheap" as the S-10s when you look at it closely, sorry if that offends anyone.
As far as quickness or speed, the '96 will outdrag my '91 4.3 I know cause I raced somebody driving my other truck at the time
The 350 with vortec heads ('96+) are quicker than the 4.3 S-10s. The 95 and prior 350 TBI trucks (200 HP only) will get smoked though!
