262 1975-76

this 4.3 liter  V8 is the smallest small block only made in 1975 and 76 has a 3.671 bore and a 3.100 stroke

267 1979-82

still called a 4.3  now had a 3.500 bore and shares it's 3.480 stroke with the 305-350

302 1967-69

305  1976-2002

307 1968-73

327 1967-69 for small journal 62-67

350 1967-2002

400 1970-76

The largest of original chevy small block family , The 400 features a 4-1/8 (4.125) bore

and a 3.750 stroke ,

unlike the other small blocks the 400 used a shorter rod 5.565  and even a larger main bearing size were built in both 2 bolt and 4 bolt mains.

Because of the large main journal size bearing spacers are sometimes used to reduce the surface speed of the bearing and allowing the use of the more common 350 crank  the result is roughly a 377 cubic inch engine 

The four hundred engine also tended to have some cooling issues do the the Siamese bores that did not have coolant between the bores  , 400s have extra holes drilled in the decks to help this problem  in the block in the heads . this is also the common place where both the blocks and heads crack
