350 Been Sitting Since 96

I Have A 350 That Has Been Sitting Complete Breather And All In A 1970 Model Gas Burning Bus Since 1996 It Hasnt Been Turned Over Or Anything Since Then I Was Wondering If Anyone Had Any Ideas On What I Should Do To This Engine To Make Sure Its Ok Before I Drop It In Place Of A 4.3 In My Monte Carlo

Thanx

Is it carburated or is it fuel injected

it is carbed with no emmisons crap and is in a 1970 model bus the original motor was a 307 but my grandpa changed it in 1994 to the 350 before he died

hell its a 350. New plugs, clean out the carb and it should start right up.
