Hey there, I am having a hard time making a decision between getting a 2014 Shelby or a 2014 GT. If I got the GT I would put twin turbos and cams on the car, I would like to accomplish around 800rwhp. Here is my question: How much HP can a factory 5.0 take? Including the block, tranny and rear end. Any advice or information that you may would know help a bunch. Thanks for everyone's knowledge in advance. Look forward to finding this information out.
