EngineLabs handed two teams an identical $9,999 budget and one instruction: build the strongest engine possible, Ford’s Coyote for one, GM’s LS3 for the other. The result is less a definitive winner and more a clinic in budget-build tradeoffs, big pushrod displacement against high-revving overhead cams, cheap aftermarket parts against premium modular components. Even the comments split along brand lines, with one self-described “Ford guy” breaking ranks to praise the LS3 outright. Watch the full build to see which philosophy actually made more power for the money, and decide for yourself which side of this rivalry your own garage falls on.
