Late 1969 saw the 396 cid engine increase to 402 cid via an increase of 0.032-inch cylinder bore from 4.094 to 4.126. These engines can be identified by a 3-letter suffix code noting the same horsepower and transmission type. For example a 396 with the suffix code JA would be stamped with CJA.

A few things should be mentioned about the 1969/1970 396/402 cid engines. Towards the end of the model year the 396 cid engine was increased to 402 cid. Rumors abound for the reason of the 402 cid existence. One is that Tonawanda has a lot of bare blocks rusting away and decided to bore them +0.032 to clean them up. That's just crap and GM wouldn't do this.

It is believed the increase in bore size was done in preparation of 1970 (when all "396" cid engines were really 402 cid) because engines over 400 cid had lower restrictions on smog regulations. Whatever the reason the 'new' 402 would become the base engine in the 1970 SS396 option even though it was the larger 402 cid engine size.

GM had a lot of marketing invested in the "SS 396" moniker and kept it for the 1970 model year. This 402 cid engine was also used from 1970-1972 as RPO LS3 and referred to as either a 400-4 or a Turbo-Jet 400 to distinguish it from a newly introduced 400 cid small block V8 referred to as either a 400-2 (as it was only available with a 2-barrel carburetor) or a Turbo-Fire 400. The small block version of the 400 cid engine was only available in full size Chevrolets and the 1970 Monte Carlo.
