Exhaust tappet
An exhaust tappet from the bottom-end tappet/oil pump assembly, also cataloged under the older E8804 number.
The 70-8804 is an exhaust tappet listed in the catalog under the older E8804 form, which is worth knowing if you're working from a period parts book and only find the letter-prefix number. It shows up in the figure covering the oil pump, release valve, manifold and tappets, which puts it down in the bottom end of the engine rather than up top in the head.

Tappets like this one ride against the camshaft lobes and transfer that lift up to the pushrods, so they take a lot of wear over time and are worth checking whenever the timing chest is open. Our catalog record for this one is thin - just the one appearance, tied to 1968 - so if you're trying to match it to a specific model, give us a call and we'll work through fitment with you before you order.
