Naturally aspirated big block V8 engines are well known for their very broad power and torque curve. We recently spotted this street engine in the build by Haddad Race Cars & Engines. The 638ci unit features new to market CID cylinder heads and intake manifold as well as an Aussie ICE ignition system. The Chevy will be fitted to a Holden Hq 4 -door street car and owner Kim was hoping for close to a four figure power reading as this Haddad built engine didn’t disappoint!
