I've had my vehicles sit as long as 5 yrs (garaged)....I change the oil/filter, antifreeze,fresh gas, fill the carbs with gas thru the vent tubes, and I fill the engine with oil just before I light it off, so as to flood the cam/lifter valley area....never had an issue with the 10 vehicles I've owned over the last few decades .... I just started up my daughter's "new" to her, 1961 Fury/Bev that sat for 20 yrs in the owner's garage untouched, last year, granted it needed a new tank/lines/fuel pump/carb,....but the motor turned and fired right up with zero issues with a new oil/filter/ and antifreeze after a generous block flush..zero issues for the motor.
