Recently bought a timing cover off the forum from a member. He told me when I purchased it that it was either a later model cover or one for a V6 as it had the bolt on timing mark. Mine is molded into the cover. My question, is there a difference between the water pumps from the later model 350 and V6 engines? Mine is a 71, I would have used mine but most of the holes are stripped out and few are broken inside the housing. I reused my water pump as I recently replaced but when I tighten it down it’s hitting the back of the cover and won’t let it spin.
Anti seize is your very good friend when your putting steel bolts into Aluminum anywhere and on anything!
I sold the OP the timing cover and am baffled here as I thought the water pumps & timing covers would interchange - My last 350 build had a NOS v6 timing cover but that was a long time ago. In fact, I have an NOS v6 cover here now (no molded tab - IDK if the later 350 covers still used mollfed tabs ot not) & an NOS 350 cover (molded tab) & an earlier NOS water pump. I'll try them & see if there's an issue or any difference in the depth of the cavity.
