Sorry for delayed response, I have a whipple SC Brian Tooley cam, kooks, LT headers "cated" Borla all the way out through S type mufflers. Next I'm going to do 750 hp 6L80E tranny and 2600/2800 SP torque converter upgrade soon. ATI super balancer on the crank. I have the complete BMR rear components and 1000HP shafts ready to go in but no time yet to install. I changed the break rotors to drilled and slotted with CF/Ceramic pads ( love them almost no dust ), Radium catch can. upgraded fuel delivery/pumps. Still a work in progress!
