With that being said, Roller for Roller the Gn has far more value then the regular regal and can be converted back to the Lc2 platform to some degree weather it be a non-matching numbers lc2 or a 4.1 v6 turbo and retain %75 of its value, if its a top notch turbo LS swap its worth %40 of its value and any other sbc drivetrain its worth what it would be as a roller. imo
