First of all lets not call the LS engine a Chevy

Chevrolet does not deserve any credit for those engines

. It is a Corporate GM engine manufactured by "The GM Powertrain Division" and was used by all GM divisions. I'd rather see someone stick one of these in their GMC rather than that ubiquitous small block 350

Just whatever you do don't give up on the 478 project because you'll have something that's different yet pure GMC and will have more than adequate power
