View Full Version : N* hp over the years...

My N* is just a tad over 100k and I'm just wondering how much hp do I expect to loose after that many miles? I saw a commerical about Castrol's high mileage engine oil, I might wanna try it out.

100K is a low milage North*. Ask again when you get to 250K.

yeah, I've seen some pics on here of Northstars opened up after 100k, and there's still cross-hatching on the cylinder walls.
When I had my 472 rebuilt at 94k miles it still had cross hatching on the cylinders as well. They still build Cadillacs well!
