Build the car around the motor, not the motor into the car. Chassis bracing/stiffening, driveshaft loop, reinforce & weld up torque boxes, and/or mildly cage it to keep from pretzeling up the body. Complete aftermarket suspension overhaul to keep the power planted to the ground. Having all that power will do you no good if you can't hook and keep the car straight. Do it right the first time or else you'll be breaking and fixing other things unnecessarily.
