I'll second that. Although I have only owned 2 vehicles with the 4.3L (my Bravada and an '89 S-10), the 4.3L is a rock solid motor. Right up there with the 3.8L v6 in terms of reliability and the overall life-span of the motor.

I have a 2000 Blazer 4x4 with 165,000 miles. 1996 vw passat tdi with 190,000 miles and a 1990 Jeep Cherokee offroader with 175,000.

 

We have some pretty high mileage truck around here.
wonder if there is some truth to the slogans. Built to Last, or was it Longest lasting trucks on the road, or was it Like a Rock?

How about the flip side, I saw one old truck with what I would consider very low miles. Anybody else?
My wifes '03 Cavalier just broke 20K.
My sons '90 Ranger has 116,000 on it.

 

250,xxx and climbing on a 95

 

92 blazer: 254k
