Later CJs got SCJ pistons.
By Dave Shoe - 11/20/2001 8:43:27 PM; IP 12.2.11.131
As soon as the SCJ cast piston became available in early November 1968, both the CJ and SCJ inherited this reinforced design.

After initial testing, the new SCJ piston was tweaked in late December 1968, and the CJ and SCJ engines after that time got the revised, even stronger, version of the SCJ cast piston.

CJ and SCJ engines did not get identical pistons specs, however. Since thge SCJ was intended to rev out farther, the SCJ piston got a looser fit in the cylinder bore, therefore a standard grade SCJ has a slightly smaller diameter spec than a standard grade CJ piston.

JMO,
Shoe.
