The L05 is the same engine as in my '89.

Here's info from Wiki.....

The L05 was introduced in 1987 for use in Chevrolet/GMC trucks in both the GMT400 (introduced in April 1987 as 1988 models) and the R/V series (K5 Blazer, Suburban, and rounded-era pickups formerly classed as the C/K until 1986 which includes chassis cabs and 4-door crew cabs) L05s were first used in passenger cars in 1989 with the Chevrolet Caprice 9C1 police package (the L05 was not available on the standard (civilian) Caprice and Caprice Classic).

Although usage was for trucks, vans, and 9C1-optioned Caprices, the L05 was also used with the following vehicles:

1992/1993 Buick Roadmaster sedan and station wagon
1991/1992 Cadillac Brougham (optional engine)
1993 Cadillac Fleetwood
1992/1993 Chevrolet Caprice Wagon (optional engine)
1993 Chevrolet Caprice LTZ
1992 Oldsmobile Custom Cruiser Wagon (optional engine)
L05 usage was replaced by the GM LT1 after 1993 in GM B-Bodies until production ceased in 1996.

In mid 1996 the L05 was equipped with Vortec heads used in the 1996 G30.

Nothing HO about it. Maybe he's thinking "HO" cause it was part of the 9C1 police package.
