Yea I couldn't stand the wait the other day and ran it up to 4500 rpm on the highway for a second. I'm thinking I may have to get some depends before I really romp on it!
You got tall gears, great for a storker. I got 3.91's for my 340 and its @ 4,000 rpm's at 75 mph--which is normal freeway speeds, you will get pass after so long.
Quieter mufflers are a big help to make it feel more smooth, I noticed that when i changed out the mufflers.
When i broke my engine in I ran it for 40 mins to break the cam in, changed the oil, drove around 400 miles and changed the oil again. Only after 500 miles did i really start beating on it--hello 6,500 rpm on the freeways, lol
