If the past has shown us anything, it is that readers of Super Chevy relish their small-blocks. Not that we don't show equal love to their big-block brothers, but there is something about a Mouse motor thumping out serious power that really gets the blood pumping. Loyal readers will remember the Major Mouse and Danger Mouse series that covered all manner of small-block performance. Though the original continues to fill the engine bays of countless performance machines, we decided to take an in-depth performance look at the current Gen III (and Gen IV) small-blocks, better known by enthusiasts as the LS engine family.
