the doctors on here probably have the answers for this but.....I know most of the small block engines up to around 1986 are pretty similar. You could trying to identify the engine. Back of the drivers side head (on the block) will be a casting number. You should be able to search for "chevy engine identification" on google and find the number. That should narrow down your choices. Hope some of this helps.
