My Dad had an '85 S-10 Blazer. Bought it new. Drove it 165,000 miles without any trouble whatsoever. 2.8L with a 5-spd. One of the best rigs he claims to have ever owned.
He also had a '91 K1500 that went 205,000 miles on one waterpump and a starter motor. He overloaded it regularly, and drove the crap out of it.
He is a devout Chevy man. And I don't blame him, he's had great luck with them.
Every manufacturer has their problems, and every person stands the chance of getting a problem rig. I usually don't stand for a bunch of Ford is better or GM is better BS for very long.
Everybody knows that with the GM 2.8L V-6, you were rolling the dice on whether you got a lemon or a stalwart, great little rig. It was so with the Ford 2.8L, also, as it is also true with the 6-liter diesels. I've never seen anyone have trouble with the GM 2.8L V-6, personally. I did have LOTS of trouble with my Ford 2.8L in my old Ranger. That didn't sour me to Ford. I was smart enough to see that I just got unlucky.
That said, GM replaced the 2.8L with what is, IMHO, the best mini-truck V-6 to ever hit the road, the 4.3L. Those things are powerful, reliable, and they run forever. Ford, on the other hand, replaced their 2.8/2.9 series with the 4.0 V-6, with aluminum heads that warped off the block ever 20 miles or so. My wife's old Ranger was a nightmare. She got it a little hot, one time, (towtruck driver said it was on the high end of normal, he was following her on the freeway and pulled off behind her when she pulled over, so it was not THAT hot) and we had nothing but trouble from that point on, to where after 3 headgaskets, and 3 head shavings, I just replaced the heads all together, to the tune of 1,200 bucks. Guess what? Next trip, on the way home from Texas, the headgaskets popped again. Coolant in the oil. I was sleeping in the passenger seat. I woke up to a horrible knocking sound. The rest, as they say, is history....
As far as getting them hot, my buddy drove his 4.3 GM in the red for 25 miles to make it home one time. Let it cool off, and it was none the worse for wear.
But, i still drive a Ford. Do you think maybe that is because I'm not silly enough to condemn an entire manufacturer simply because of one lemon? They all make 'em, you just have to be lucky enough not to get one...
