hi all,

were all early 289/302 timing covers (any that use standard rotation water pumps) aluminium as stock, or were some iron? and at what point did the dipstick locator move from the front?

cheers,

Mark

All aluminum on the Windsor engines. Supposedly, they moved the oil dip stick in 1974 but my 79 F150 oil dip stick is still in the timing cover. I believe it has a 74 block. It may not be the original engine too.

That is going to make it a bit difficult for me since I need a new timing cover and a new water pump. Not sure what to order. I may have to take my water pump off and go to the parts store with it to get a match.

Dipstick in the timing cover change as the vehicle went to a rear sump pan. So it varied some depending on the vehicle. Some front covers still had the boss but not drilled drilled out.
