If you are doing gears, I suggest doing 4.10s. 3.73s aren't enough of a jump from 3.42s to justify the cost, IMHO. I've got 3.73s in my 6.2 CCSB and I wish I had 4.30s with my 33s; 4.10s would be perfect on the factory 32s. Also, the LS9 cam takes away from your low-end powereband, so you'll want the extra torque.

2011 Chevrolet Silverado Ltz Ls9 Camshaft Swap Dyno Photo 20

Notice how the graph starts at almost 4000 rpm and at that point the LS9 cam is making less power than the factory cam. I wish they plotted the graph from 2000 rpm and up as I have read on this forum and others that the LS9 cam offers substantial increases up top but down low it is soft.
