Enlightenment.....Please!
I believe none. Somebody correct me if I'm wrong, but they used the Vortec based more off the old Gen 1 350 until they started using the 4.8 and 5.3 L LSx based platform. Never put an LT1 into a truck, although I've seen a Tahoe with one stuffed in there and it was a fun truck!... It was not factory though. LOL.

(although I don't think the truck engines ever went to reverse cooling like the LT1's had).Heck, they even make aftermarket carb manifolds for Gen-I SBC's so you can bolt on a set of Vortec heads, they were supposed to be that good?
