It’s been a while…273 build.

G’day. I’ve bought this type of harmonic balancer, with the timing case pictured, balancer is 7’3 inch diameter, looks like it will hit the timing marks on the timing case before the balancer will go all the way on.
Any ideas?

The early 273 timing cover uses the bolts on timing tab, not the casted one as pictured. 65

The water pump discharge will obscure that cast timing tab.

The bolt on places the timing marks on the other side.

Up to thru 68.

But the bolt on timing mark might also interfere. You may have to make a custom one.

Ok, I’ll add I have a late model water pump too. Maybe I’ll re ask the question “ what timing cover do I use for a 7.3 inch balancer”….

“ what timing cover do I use for a 7.3 inch balancer

As mentioned 68 and older does not have molded in timing mark.

the bottom hose is the other side on the later pump so the radiator will need altering/changing out.
neil.

Without power steering you can JUST see the marks on the driver's side with the cast iron water pump.

I have a stock 67 273 with a 70 up cover so I have both marks, AND on a side note the two are not 90 deg apart. So if the marks on the damper are designed for a pre 70 SB they will be off with the 70 up cover and visa versa.
