Original Oldsmobile 330 engine (381917A1) from 1964. Has #3 heads on it and comes complete with oil pan, pistons, rods, lifters, valley tray, water pump, and oil filler. Comes with matching crank (388776). All original and standard bore - never machined. Will obviously need a rebuild. Looking for $400 - I'm in Atlanta and can travel a little to meet up. Let's work to get this beast in your classic Olds!

 

1964 was the first year for the 330 (#1 heads); the water pump was unique to the year, had the inlet on the driver's side (one year only). #3 heads would have been original on a 1966 330. Check the water pump for the inlet orientation; maybe you have a mis-matched set of heads.
