		| 410 pistons come with both a C6AE and C8TE number. |

		The later C8TE 410 pistons which were installed in 390 light pickups to achieve about an 8.5:1 compression ration retained the "410" number markings on their side.  This would be a commonly available piston.
  I'm not sure which year 390FE light truck engines they would be available in, but I suspect the C8TE number indicates they were available in 1968, and they were probably used until 1972 or later.  I believe the compression ratio of the 390FE light truck engine dropped a bit further as the 1970s progressed.
