Introduced in 1970, the 402 cu in (6.6 L) was a 396 cu in (6.5 L) bored out by 0.03 in (0.76 mm). Despite being 6 cubic inches (98 cc) larger, Chevrolet continued marketing it under the popular "396" label in the smaller cars while at the same time labeling it "Turbo-Jet 400" in the full-size cars.
Its solid-lifter cam, known as the "30-30 Duntov" cam named after its 0.03 in (0.8 mm)/0.030 in hot intake/exhaust valve-lash and Zora Arkus-Duntov (the first Duntov cam was the 0.012 in (0.3 mm)/0.018 in (0.5 mm) 1957 grind known as the '097, which referred to the last three digits of the casting number) the "Father of the Corvette", was also ...
The 302 cu in (4.9 L) version of the Lincoln Y-block was used for heavy-duty truck applications from the 1956 through the 1963 model year. [4] The engine had a bore of 3.625 in (92.1 mm) and a stroke of 3.65625 in (92.9 mm).

The engine was available in all full-size Pontiacs.

Overbore cartridges are those with a relatively large case volume or case capacity, coupled with a relatively small diameter bullet.. The case volume or case capacity and barrel bore area can be mathematically related to obtain a case volume to bore area ratio in metric or imperial units.
1968 and 1969 400s shared the Olds big-block standard 4.25 in (107.95 mm) stroke with the 455 but used a undersquare 3.87 in (98.30 mm) bore to comply with GM's maximum 400 cu. in. displacement restrictions in the A-body cars while also reducing tooling costs. Displacement is similar to the earlier engine, at 399.9 cu in (6,554 cc).
