Another Holden custom rebuild 357 Cube VN style Hydro Roller engine shipping, we reused as many of the original parts as possible, small cam, small compression, but with precision machining and the addition of only our Version 0 standard valve factory OEM Cast Iron CNC heads that provided a massive average torque of 433 FT LBS from 4000/6700 RPM with a good peak of 452 FT LBS, and equally good peak power of 516 HP at 6700 RPM with very very conservative tuning on PF 98. Exactly what this customer wanted.
