I have a 1995 5.0, could the engine being unbalanced cause the engine to shake, and max out at 3500 RPM? I took the car to a local shop and they said that that was the problem. I would appreciate any help thanks.
ATI is probably the best. But it's gonna cost you.
I'm also a fan of the ford racing balancers, there's 2 types, stock style replacement and then there is the steel kind (better).
If money is tight a new stock replacement is fine IMO .
