PISTON COMPLETE (7.4:1)
Complete 7.4:1 compression piston listed in a 1980 catalog entry for the crankshaft and connecting rod assembly.
This is a complete piston, listed with a 7.4:1 compression ratio, from a 1980 catalog entry. "Complete" in the parts book usually means the piston comes assembled with its rings and gudgeon pin rather than as a bare casting, so what you're getting is the whole unit ready to go into a bore.

The catalog places it in the crankshaft and connecting rods section, which is typical for pistons since they're listed alongside the rotating assembly they work with. Beyond the compression ratio and the single model year on file, we don't have more detail tying this to a specific engine size or model.
If you're matching this up to a rebuild, check your bore size and existing compression ratio before ordering, since pistons in this era were offered in more than one ratio and the numbers aren't interchangeable. Call the shop if you want us to confirm fitment before you buy.
