how come the specifications page lists that the standard engine on an 87 K5 was a 350, but the sticker in the engine compartment of a K5 that I looked at said that it had a 305 in it? Was it like an economy option that the original owner may have done to save money? It has power windows, locks, tilt, etc.. and dosen't appear to be bare-bones... I may be able to provide more info about the Blazer if its needed. Thanks for any help.
