The truck I bought for my son to drive to work ('89 Chevy) has the 4.3L and has over 300,000 miles. It is still running, but it in need of some attention. As it is a work truck, he has not done much, but reg. oil and filter changes and putting gas in it. It still runs pretty strong though.
as it being that the truck only has 22,000 miles nothing needs to be replaced but i would like to get the best out of it..my olds bravada i had when i sold it had almost 400,000 miles on it and it is still going...im just looking for ideas of what i can do to it to get the most out of it thats all
I have the 4.3L V6 and I have been told that to beef up the engine, I should do: a cold air intake, performance tune, and exhaust system. Anything after that (like headers ect.) wouldn't be worth it because of little HP gain, and lots of money spent. Those three things will get you going fast. I would consider a Supercharger/ Turbo if you want speed, but then again it's a V6 so it's really pushing it. Good luck, if you get a air intake, please post the results, I am seriously considering buying one!
