But discovered that I don't know if I have hydraulic lifters or not. Here's what I found on the engine:
Flat plate behind distributor: F410A
On block above starter: CON40 AD 57 (not sure if it's an A or a dimple).
On cyl head above intake manifold: 3836848 GM10
On block below distributor: 383004
On cyl head above plug #3: B50 848/850
Hopefully this provides enough info to ID.
Appreciate any help,
Mike | | |
