For the street I recommend a steel flywheel, 10.50" 130 tooth which will fit into the stock bell housing, a 143 is an 11.00" and won't fit.

Call Wayne Brewer or Jamie Passon for a clutch, I recommend a stock style McCleod (roughly $600-$700.00 a set).

All 1968 through early 1972 340's were originally equipped with a forged steel crank and are internally balanced, later date 340's equipped with a cast crank were externally balanced.
