Will give it a try, my stroker rarely/ never sees above 3000, always afraid it would want to eat a rod. Will have to do some driving in 3, otherwise it almost never sees 2500. 70mph is only 2100-2200. What makes the valve rotate and why only above 3500

You need to get over that stuff.
DRIVE IT!!!
Factory shift points are 5000 RPM at WOT. It's not a truck motor. A 4.6L motor was built by AMC in South America/Mexico. It isn't gonna blow up. No more than a 258 if you think about it. The 258's redline is upwards of 4500 RPM. Quit being shy and use that motor.
I'll second this, mechanics, as well as myself, have been doing this for years
What RPM do you rev your stroker to?
I revved the Jeep Racing Comanche with a 4.6 stroker and supercharger to 6000 regularly. so did everyone else who test drove it. Took 5 years to throw a rod.
I drive 30 miles at 70 mph in the morning and today I tried to get the rpm's up. In D im turning 2100, in 3 that jumps to 2700...I didn't want to drop it into 2 at 70. On the sidestreets i was able to drop it into 2 but even at 50 mph I couldn't get to 3000. I am driving 31's on the stock 3.55 axles..Its almost impossible to get that damm thing above 3000 rpm.
I know its been 2 years but I have finally found the cause of this. After countless trips offroad, up and won the east coast, the gas mileage was awful and it started running rougher at idle. Took the head off and found Cylinder 1 Intake valve was not seating sometimes because of a massive chunk of hardened carbon on the valve seat and a section of the valve. Exhaust valves 1-6 were all badly pitted. Headgasket between 1 & 2 was on its last legs. After new valves and cleaning up the seats at home it runs fine. Hopefully it will make it past 300k now. bc
awesome you found the cause. Question tho when it would misfire would you be around 50-70 2k-3k rpm and it would misfire a few times? If so your cause is likely to be whats going on in my jeep.
