jddmj Posted February 9, 2015 Report Share Posted February 9, 2015 5.3L? I don't know much about Joe Gibbs trucks, but that doesn't sound right to me. Especially if he's claiming 425 horsepower... I retract my last statement. I always assumed the joe Gibbs trucks were just a tricked out version of the ss since they look almost identical. No, the single cab was a 4.8 paired with a 5 speed, while the 5.3 was an automatic. I think they all had the supercharger, but I could be wrong. The ext. cabs all had 5.3's. That charger might bring the pony numbers up to that kind of par, but its hard to tell without seeing the dyno numbers. Quote Link to comment Share on other sites More sharing options...
1BAD2K Posted February 9, 2015 Report Share Posted February 9, 2015 Supercharger was an option. Quote Link to comment Share on other sites More sharing options...
zpierce Posted February 9, 2015 Report Share Posted February 9, 2015 I thought he had an entertaining write up at least..till I saw this article written exactly the same lol. As for the 425 I believe it. My 5.3 put 375 at wheels so at motor is around 450 depending on how you calculate.. http://www.superchevy.com/features/0408sc-joe-gibbs-silverado/ Quote Link to comment Share on other sites More sharing options...
