Did you over rev it or did it run away Matt?
Only other way I know is if you sheered the pin in the cam gear and it slipped position.

Id agree. 3rd gear pulling we have hit 3800-4 pretty easy. 3500 wouldnt be enough room.to i know alot of guys that hit 38-4000.
I set mine to 4400, is that too high for stock valves with heavy springs? Not that its been that high for very long.
Thats insane....I wouldn't do it on a stock valve train....especially if you havent ever even adjusted the valves.
38-4000 isnt too bad....no way I'd go to 4400 on em.
Valve float is a killer.
I have 110# valvesprings. Last pull I ran up to 3940 in 3rd gear on the pulling track. I don't run that high, just set a limit incase I broke an input shaft or something.
Alot of guys turn high rpm pulling. Idk what the most would be for duramaxs but I've seen dodges turning 5, and there an inline 6.
Almost every person i know that pulls doesnt keep the stock rev limit. Cause most of the time if u have the power, the truck speed gets up there and the gears run out and u bounce off the limiter. Thats why most try and run 33s. I know some that bumped to 35s to help.
It is going to exceed that limiter pretty quick if you break something. I know what you are saying but the fuel is already there for it to keep revving.
