Oil pressure gauge in '67/427

My '67 427/390 only has a 60 lb max figure on the oil pressure gauge. As
I recall, a '65 327/300 I used to own had an 80 lb gauge (might have
been a 90#... it's been 20 years since I sold the car).

My reason for asking is that when accelerating it's pretty easy to peg
or nearly peg the needle at 60 lbs. - otherwise, at idle it sits right
about mid-point at 30 lbs.

Might anyone know offhand if the 60 lb gauge is the correct one for the
427/390s? Might there be any problem indicated by the high pressure
reading (according to the range given on the gauge) on acceleration?

On my original 67 390 hp I will peg at 60 pounds when cold but after it
warms up it will drop to around 55 pounds under acceleration. At idle
it may drop to 45 pounds.....

My 67/390 had a 60psi gage and I replaced it with an 80psi from Corvette
Central after I put a high volume pump in.

Thanks ddodero and 67RATT, I guess I've got the right one in there.
Anyone know the high pressure mark for the 327s of the '63s to '67s?
