stock bottom end 5.3 safe max shift rpm's

[2007L33]

7300 " FTW "

back down to "7100" stock bottom end

been running it forever!!


personally i wouldnt do it on a high mileage truck, but then yeah i probably would lol

I'm the same way I guess truck has a 100k powertrain warranty anyway ? I bought a 2500hd 6.0 in 2002 and truck pulled it in the stock class for 4 years with 200hp nitrous on it and it never missed a beat. I sold the truck with 212k on it and it had exactly 302 10lb bottles thru it ! I have a friend I put a solid roller in his 01 camaro with an l92 carbed topend he spins it 7800 thru the traps. Its still together but its starting to rattle a little.

I get paranoid sometimes cause my first engine in my Camaro was a 408 I will not say who built it as I think they are a sponsor and its most likely nothing to do with them, But it was $5800 for the short block I went for the Lunati crank and Rods and wiseco pistons blah... blah.... Long story short I had a rod break just above the journal ? with only 20 passes on it shifting at 7000 no nitrous.
