I've got about 100 miles on my 1500 engine now, and have managed to get it in a pretty good state of tune. It is using the same intake, exhaust, and cam that my 1300 had. The 1300 liked to pull past 8K, and back in the day, the common knowledge was that the 1300s held up just fine with excursions up into that range. This new engine seems rather eager to rev past 7K but I am trying to be a little conservative until I get more information. The bottom end is completely stock to the best of my knowledge. What is considered a reasonably safe upper limit for a 1500?
