hi, i just got a 91 1500 excab short bed 4x4 with the 5speed manual and the 4.3L V6 and i know nothing about this truck. it has 113K origional on the truck. i was wondering how much HP/Toruqe this thing puts out. what are some things to look out for? i know the exhaust rattles real bad, but i am thinking about putting a 3" flowmaster on it from my old ford.

what are some good aftermarket parts for this. im always looking for more power and more gas milage out of it. it has a k&n filter in it right now. i was looking at chips for it, but they are pretty expensive for the power gains.

thanks,

second day i own it and the altenator went out and took the serpentine belt with it. oh well. anyone know any of any good fan replacements? i think this one is shot, when the belt went it jammed the fan and now the fan is real loud.

That motor makes 160 hp and about 200 lb/tq at the flywheel and about 100 of it only makes it to the rear tires.

My opinion, keep it stock, adding exhaust to a TBI 4.3 is just going to leave you with less money in your wallet and people laughing from the noise.....

Go with the stock fan and belt, and replace the tensioner becasue those have been known to loose their tighness.

There isn't much out there to help a TBI 4.3, you can add gobbs of crap it to but it isn't going to put out much more, even a TBI 5.7 is hard to work with unless you get into cams and stuff.

If you want more power, swap in a v-8, with a TBI fullsize truck its easy and can be done in a weekend with some help.

Anyway, good luck with it, the 4.3 is a good motor for longevity and work, they last a hell of a long time.
