[DeTomaso] 351C steel billet flywheel

Fri May 14 21:38:34 EDT 2010

Agreed, however this discussion has come up before and all aluminum flywheels are not alike, many of the cheaper versions are cut from a lower grade Al alloy and simply sliced from a large rod...... be sure to look at the specs of any unit you consider and do the cost benefit analysis.
