: Difference between 275 & 300 HP from # on Valve/cam Cover

Is there a way to figure out what engine it is by the number on the valve/cam cover?

Are 2000 plus Northstars the same as pre-2000's?

Until bbobynski can post with more detail.......I have read some of his posts stating they are different and not interchangable because of the electronics.

Not sure on the engine serial number. There is a stamped number on the block somewhere. Can't remember where I saw it. If I find it I'll yet you know.
