L05s were used primarily with casting number 14102193 (64cc combustion chambers) cylinder heads with swirled intake ports—the intake ports were designed for fuel economy (the design was also shared with the 103 heads used on the 4.3L with TBI). The swirl ports (known to GM as a vortex chamber) along with the irregular shape of the combustion ...
RPO decoder (for newer vehicles). Beginning as early as 1967, [ 2 ] and to all their models since 1984, GM attached a Service Parts Identification (SPID) label. The label is most often located on the back of the glovebox door, on the inside of the trunk lid, or on the bottom of the spare tire cover.
SBC, or low-complexity subband codec, is an audio subband codec specified by the Bluetooth Special Interest Group (SIG) for the Advanced Audio Distribution Profile (A2DP). [1] SBC is a digital audio encoder and decoder used to transfer data to Bluetooth audio output devices like headphones or loudspeakers.
The new logo formally adopts the Small Block name for the engines. The fifth generation of the iconic GM small block engine family features the same cam-in-block architecture and 4.4 in (110 mm) bore centers (the distance between the centers of each cylinder) that were born with the original small block in 1954.

There was a U.S. auto industry-wide shift to lower compression ratios in mid-1971, so AMC increased combustion chamber size to 58-59 cc. The first three digits of the casting number on the large chamber heads are 321, 322, or 323 depending on year. The only difference between small and large chamber Gen-3 heads is the combustion chamber size.
