how do i identify what year my small block chevy 350 is?

Answer 1

The most acurate way is to use the casting numbers on the backside of the engine where the bell housing is mounted.

The other option is the stamped numbers on the engine deck right in front of the right head.

Answer 2

Boy did you pull the nuts out of the wood work with this question. The engines are identical except for the main caps and the main web they attach to. All parts except the block and the caps will interchange. This is assuming the engines are of the same year as three different 350 Chevy engines were made, the 67-68, the 69-86 and the 87 up. That does not mean the Olds, Buick or Pontiac 350s nor the late model LS engines. And of those three models, most of the parts will interchange but not all. There are differences in the parts also depending on the horsepower rating but nothing that will keep a mechanic from interchanging the parts.

if it has centerbolt valve covers, it's 1987 or newer. if not, it's older than 1987.
