I have about 20 hours on my new 11 to 1 454 in my 83 sleekcraft jet. I just changed my oil and have a very fine metalic content in it. The engine is running great and ran outstanding all week long when we dragged it down to tablerock last week. Just reliable as you can expect after a couple of initial jet changes from our 6200 altitude here in colorado springs versus 960 at table rock. I put about 200 to 250 miles on it, mostly around 4000 rpm. Is this just cam break in stuff or should I get a sample done? I basically got it running and left for Missouri the next day so I didn't get to change the oil after the cam break in wich I know isn't the best thing to do.
