Hmm i own two Dvds one with all of GM's Old school ss vehicles like the ss camaros and 454 chevelles and novas and one from power block that show the teardown and build a 454 ss and a first gen lightning both say 91-94. The one that they are building was a 94 so IDK.
Heres the sight of the 454 ss build where you can buy it http://www.amazon.com/Project-Muscle-Trux/dp/B00260HELA
coming right from the link you gave...
"a hour and 43 minutes of budget builds and shootouts between a turbo '94 Ford Lightning and a hopped up '90 Silverado 454 SS."
