Safe max RPM for bone stock 5.9 magnum

i like it all except the "just not as good" part of it. LOL. Seriously, those 5.3's straight from the truck to the chevelle are not rockets. They need all the fix'ns + a ebay turbo.


True but 5.3 LS can get 500 hp with just cam and headers, most I’ve seen so far with magnum is 414 hp, magnum is more on par with older 350 vortec, still a great option for us low dollar mopar guys.
