Notes:
(C) Block grouting is not required for power levels up to 450 HP
(D) Block cam tunnel is checked for size prior to the start of the machining process. We have seen many OEM
blocks not within spec from Holden. This can cause spun cam bearings in the future through no fault
of your own.
(E) Lifter Bores-Highly recommend grooving lifter bores for added oil flow to cam on hydraulic or solid flat tappet cams
