And none of us shift at 7,000 rpm? I know I do on my car. Just like alot of Cobra owners do. How many people just add bolt ons and bolt ons and tune the car, removing the stock limiter? That is the nature of this game, you mod, mod and mod some more. Next thing you know his motor isnt stock anymore. The problem here is people try and educate and then others criticize it. That is whay alot of these professisonals stop coming to post. They try and help and no one really wants to listen.
3 of the named failures happen at 7k, doesnt mean they all did. Heck Bob Cosbys car only sees 7k at the 1-2 shift and the rest is 6500ish. Bob Cosbys engine is a 4.6, Factory Stock engine which means it pretty much was a bolt on engine. Joe Lynch had a 4.6 when it happened as did Carlos Nazeriano(if I recall)
Lets forget about the fact that it has happen and could it happen to others as well. Like I said for the price, and the potential negative effects, it's not worth the money when it can be spent elswhere going faster. Not all the motors were built 5.4's either
