i've got a 86 through 94 350, on the flywheel there is a weight on it. i've been told that its not supposed to have a weight on it b/c its interally balanced. i looked up the crank number and its a regular 350 crank. why would that weight be there???

86 and older block were external balnced engines. Flywheel/flexplates don't interchange.

The '86 and older small block rotating assemblies(except 400) were internal balanced meaning the damper and flywheel were neutral. The 400 was external and took a different balancer and flywheel with counterweights to balance properly.

The 87 and newer small blocks with one piece seal lost the small counterweight on the back of the crank. Therefore they need a counterweighted flywheel to complete the balancing. The flywheel/flexplate will not interchange between the 2 old and new cranks so you cant mix them up.
