engine sitting for 8 yrs .

[goochy]

Buying a complete 1987 K5 from buddy for $1300 . It was full rebuild 1000 miles ago , but then he parked it for 8 years !!! YES 8 years . I know the builder , it was done right , 60 over , 10 1/2 compression , cam , headers . Nice motor !! 400 plus hp The K 5 looks good , straight body , every thing is there . Baby bald tires on nice rims , K5 has 6 in lift with 3 in body . ITS BIG !! I just want tailgate and motor . Should I be afraid of engine sitting for 8 yrs ? He did drain the gas out of tank , then parked it . I am thinking pouring tranny fluid down plug holes , and mix some in gas . What do ya think ? I am going to put my 305 engine and my tailgate on it then sell it !!!!
