ok i was doing some reserch on here and was unable to find any info on this. maybe i just dont know what to type in to find it...

but...my question is what is a safe rpm that you can rev the 5.3L out to with stock internals..i have seen a few people reving there engin out to like 6800-7000 and i was thinking that they had some internal stuff done...but i ws not sure..

thanks for the help.

 

stock cam, springs rods not past 6200 in a 5.3, 4.8 i had my stock cam,springs,rods running up to 6400.

 

ok...i wasnt thinking it was much more then 6000....i do plan on putting a cam, sprigs and rods in hopefully byJune....but theres so many cams out there so i still have to do tons more reserch on what cam will work best for me....thanks for the quick reply v8 i wasnt expecting anyone to post until tomarrow sometime...

 

Everyones opinions on this may differe but I usually try to stay under 6200 on stock stuff. With cam, springs and pushrods I usually rev out to about 6500 and have gone as high as 6700 when I was N/A.

 

your welcome.

 

Spun my 180K mile 5.3 up to 6700 and it still had good compression when I pulled it.
