I've got a '99 Silverado, 2wd ECSB w/5.3L. Can I just drop in the 6.0 and drive away? What about the tranny, exhaust, wiring, radiator, etc?

I figure a proper tune would be in order. What about a torque converter, and rebuilding the tranny?

"if you're gonna be a bear, be a grizzly"...so I'd definitely be looking for an '02 LQ9.

Thanks,
Michael
