The original LT-1 was introduced in 1970...
Then in 1992 (22 years later) they introduced the 1992 LT1 with a revolutionary new system called Optispark ignition.
Now in 2014 (22 years later) they introduced the 2014 LT1 with (for the history of SBC generations) a revolutionary new system called direct injection.
I see the pattern.
