my friend is buying a 97 z71 4 wheel drive. he had a 95 which had a posi trac rearend. he wants to know if the rearend in a 97 would be as well. and how much horsepower does the 350 vortec in that year produce.

You need to open the glove box and find the RPO code for the rear axle. This will identify the type of rear end in the truck. Typically, F, G and H RPO codes are for the rear end. Posi and limited slip rears are usually preceded by a G. G76, G80, G81 and G86 are posi or LSD rears.
