I am running a 232/228 115 lsa cam with patriot gold springs and hardened push rods. Right now we are shifting the car right at 6000 rpm. This is on a stock bottom end 346 turbo car with built 4L60 car with 3.42 gears. I have been thinking about raising the shift points higher but have no clue on what the safe limit would be.

 

I would not personally go past 6500 rpm with stock bottom end.. Have you treated your cam bolts with locktite (if you don't have APR cam bolts)? They come loose easily in S/C cars.

 

ive had a couple of shops tell me 6800 is ok but id never try it without rod bolts and numerous tuners tell me that 6400 is safe all day
