After selling his twin turbo 408 cubic inch LS3 V8 powered Torana, it didn’t take long for Luke to decide to build another tuff street Holden. Going with a different route this time out the car is boosted by a Magnuson Heartbeat supercharger.
The stock stroke LS3 still retains the factory piston and rod combo but up top a pair of Higgins CNC ported heads are fitted. Making a little less power than the old car, the current Torana has an extremely usable torque band both on the street and at the track. Once again backed by a HASTY auto trans built Powerglide transmission.
