Oh yeah. Hehehe. Though at that point in these trucks (the Caprice / Impala guys have to do it too) you're looking at either going to the T-56 6 speed stick, a 4L80E, or a T400 with a Gear Vendors overdrive...that is, if you still want overdrive...that kind of power with this kind of weight tends to eat 4L60E's alive, even rather well built ones.
Maybe I can convince my brother, whenever (in another 80,000 miles, lol...synth rocks!) the LT1 finally needs to come out of his '94 Z28 for a rebuild, to go LT4 on it...hehehe...
