Richard:
A higher pressure cap will be better at preventing a boil
over if your car has a tendency to overheat.
I suspect that the lower pressure cap was an emissions
consideration, i.e. trying to keep the engine temp in a narrow
range so that the carburetor calibrations would remain accurate.
If it were me, I would pop for a new cap. They are cheap,
and if there is a problem, the $5 saving from the used cap
would hardly seem worth it.

Subject: Cooling system pressure question....
The radiator cap on my '72 is showing some wear (inside brass cracked
and
missing in places), so I went to get a replacement from my '73 parts
car.
Both were Stant 'Lever-Caps', but the '72 had a 14lb cap while the '73
had
a 7lb one. I also noticed in LMCs current catalog they called out
different pressures for different years, but will there be any problem
with
using the LOWER pressure cap on my '72 ?
lurking in digest mode,
