PISTON COMPLETE 11:1 C.R.

A complete 11:1 compression piston listed in the crankshaft and connecting rods section, also cataloged as E6867.

PN · 70-6867

70-6867 is a complete piston listed at 11:1 compression ratio in the crankshaft and connecting rods section of the parts book. It shows up under the older E6867 number too, so if your book still uses letter prefixes, that's the same piston.

This is sold as a complete piston, not just a bare forging, so expect it to come with the usual ring set and pin hardware that a complete piston assembly includes. It appears in catalog listings spanning 1967 through 1970, though we don't have more detail on which specific models pulled this part in that window.

High compression pistons like this one change the way an engine runs compared to stock compression, so if you're building toward 11:1 make sure your head, cam, and fuel plan are set up to match before you drop this in. Give us a call if you want to confirm fitment against your engine before ordering.
