The engines with 2.5 L (2,490 cc) displacement, identified as the Volvo Penta AQ151 (8 valve) and AQ171 (dohc 16 valve) models, got a forged crankshaft with a longer stroke of 86 mm (3.39 in) together with pistons with a 3 mm (0.12 in) lower compression height. The 2.5 L (2,490 cc) blocks still had B230 cast in the block.
A 307 cu in (5.0 L) version was produced from 1968 through 1973. Engine bore and stroke was 3.875 in × 3.25 in (98.4 mm × 82.6 mm). All 307s had large 2.45-inch (62.2 mm) journals to accept the 327's crankshaft. Pistons used with the 307 share the same pin height as the 327 but retain the 283's bore size.

[82] This engine replaces the unrelated 4.3L V6 whose lineage dates back to 1978.
