well if its a really low compression motor looks like it mite be a good turbo motor or nos motor , the bottom end is already forged steel , yeah it has those ugly [Edited by Moparts - Keep it clean] water pumper heads on it , when i picked the motor up the guy told me it was a 440 , i got for $200 and payed $90 in gas to git there and back , so when i found out it was a 413 i was much happier finding out it has all forged steel internals , i feel like i stole the motor from the guy
