80 lb oil guage question

[402Bowtie]

I know the 80 lb guages were only offered on C40 and bigger trucks, so what kind of engines are people running that require the 80 lb guage? Why do some people seek out the 80lb guage over the stock 60 lb? I assume there are many engines today that require more than 60lb oil pressure?

I have a mostly stock 402 BBC I plan to run and am wondering if I should use an 80 lb guage....

Thanks for any info!
