Sandman had the same optional engines as the normal commercials they were based upon except HZ where Sandman was standard with 253. So this means:

HQ - 173 (H&L), 202 (H&L), 253 (H&L) or 308.
HJ Holden (early) same as HQ. Late HJ the base was 202.
HJ Kingswood - 202 base.
HX 202 base, low comp basically gone.
HZ 253 base.
