yes but they have different cam lobes from 98-00 and 01-02 for Fbody's. Corvette TB's are same size but use electronic trottle. I believe the truck 6.0 units use a bigger TB.
But there's little point putting a bigger TB onto a stock LS1/6 intake manifold as the inlet hole on the manifold isn't any bigger. Stock ported TB's work well, else look at a 90mm setup such as the FAST 90 intake and NW 90mm TB.
