i am just wondering what problems could this cause? and what whould be my best options a rebuid? or.. thanks

depends how long the car has been sitting... how many miles on it... so on and so forth... you'd probably want to change the plugs, fuel filter, might want to take a look at the cap/rotor and wires as well.. belts might need changing as well depending on how long it's been sitting... does it run?

i do not think so, i have not gotten the car yet, waiting on a few things, the engine is complet IDk if it runs or not i would think not its been sitting in a lot for at least 3 years

Change everything! Better now then later!

Check for rust!

yup cant wait to start doing body work on it, and i plan on gitting a rebuild kit, so it should be fun rebuilding the engine :D
