Re: Gen VI,mark IV crank timing help please
 

Is your engine going to be internally or externally balanced? All Gen 4, 5 and 6 flywheels and balancers are for external balance. With your stroker crank, I would think you would be going for internal balance. Which would mean replacing your
harmonic balancer and cutting all weight out of your flywheel for neutral balance. :rolleyes:

Is the balance associated with the crank?Do cranks come nuetral,internal or external balanced?If i use a Mark IV flywheel does that mean i use a Mark IV balancer or is this in relation to the crank?

when replacing the crank shaft it is neccessary to rebalance. there are two methodes of balance, external & internal you & your engine shop should decide which is best for your parts combo & use . balancer & flywheel are different for each & never mix , external balance flywheels can be cut to neturel & used for internal balance motors.
