The GOAT! The GTO, with its rich pedigree was reborn in 2003 as 2-door wolf in sheep's clothing. Available in both LS1 (6.0L) and LS2 (6.0L) versions and with automatic and manual transmission options the Pontiac GTO was a great coupe with growth potential. Power-wise the LS1 made 350HP/365TQ and the LS2 400HP/400TQ. Regardless of which version you've got if you just scroll a bit we can probably pack some extra HPs and TQs on your ride.
