Can u tell if its a 305 or 350 from outside?

How can you tell if a motor is a 305 or a 350 without tearing it down?

yea you can.... the exaust manifolds on a 350 run below the spark plugs, and the exaust manifolds on a 305 run above the spark plugs, in kind a arch shape from exaust valve opening to opening

Best way to tell is the manifolds, providing they haven't been changed. On MOST 305's they stamped the "5.0" on the back of the block just in front of the bell housing on the drivers side.

Pull the casting # off of the back of the block by the bellhousing, then go to NastyZ28.com and look it up.

Get the casting number from the top of the bellhousing boss behind the drivers side head, then check it out here:
