Tom, Starting '62 thru '68 small journal 327 forge cranks could be identified
by the crank snout. If factory drilled and threaded for a bolt it was forged
(bolt on balance), if it had a lathe center it was cast (press on balancer).
1968 they made a steel large journel 327 crank for school bus engines.
