got some blazer questions

[michael bustamante]

nubie to this section!!! ok guys im picking up. a bone stock never been modified. 84 blazer 4x4. looks like it has power options. now this thing has been sitting for 8 years and not been started in 5. so whatam I gonna need to look for to make sure its a good block? crank turns. I know I have to change all fluids so why else should I do before cranking the engine? anything else to look for before finalizing the sale?

original am/fm tape. got the back window down but wont go back up and the tailgate lock wont turn with the key. but hey for 900 I can't complain. no rust at all as its a NM truck!! ill post pics soon
