I recently bought a 1973 Olds Cutlass Supreme. Not sure what engine I have, the vin says its a 350, but the distributor turns opposite. The # on the block, just above water pump is 395558 2. The # on the intake is 41199G D2AV. can anyone help?

 

go read 1bad68's' engine numbers for your block decoding.
