It appears that there is an LS1 in some bodies that is at 381.
Then there is a manual transmission combo that is something like 40 horsepower less than the 381 of the same body.
Then,if it is in a Corvette,you see 350.But in a Firebird, it's 381
Are these engines all the same or are there differences?
They are the same. Everyone and their brother ran a Firebird or Camaro with that combo. Corvettes didn't get as much attention until recently and they've done a good job at protecting that combo.
