Maximum RPM from a 08 5.3 liter
I have a 2008 model 5.3 from the junkyard i paid 400$ for, it runs hard on the big end with a patriot cam(225/229@.050,582/589 lift,114LSA), i put fresh 317s on it as it will be getting the turbo treatment in the future, but right now all motor,m i spin 7000, it does make power till 4250 and start pulling, but i shift at 7000 not feeling the car nose over, how much can the GEN IVs take for RPM? I have seen the older GEN III take a **** above 7000, then you have guys like me spinning my stock long block 2001 6.0 to 7200 all day.
I think 7500 is where ti wants to go, but dont want to destroy the perfectly good low mile short block and possible **** up the fresh heads, i am using comp 918s as well, so i am wondering what you guys think it will handle, bastard sounds great at 7000 and i will at least wind it to 7200 the next time i up the rev limiter, but it just really feels it needs more.
