The engine came from an automatic car and i would thefore need to find a flywheel for the car. Ive read a lot about using 7a/3b flywheels and that would work for me as Im planning to go with an efi conversion.

my question howerver is are the stock flywheels for 10v and 20v 0-balanced or are there counterweight to externally balance the engine? I have heard both yes and no to this question.

if not 0-balanced is the counterweights the same for all or some of the 10v/20v models?

i would like to stay away from opening the engine for a complete engine balancing.

best regards
