We have a moral obligation to tweak this crate engine to see if we can make it sing. But this is STREET RODDER, which means we can't leave it stock. But for the street set, simple crate engines have become the quickest and easiest path to movin' down the highway. Chevy builds those too and that LS-based 770hp LSX454R is just one example of what's going on in that arena.

The real reason is that there are just so blasted many little-block engines roaming the earth we can't ignore them. It's not because we aren't creative enough to come up with something better.
