had a quick question about how high these 4.8s can revved out to? my current tune shift points are set at 6600 if i remember right, trucks going off to get tuned within the next few weeks and i was thinking about having the shift points set at 7k? thing is idk wether dragging the revs out will actully benefit me or hurt me in the 1/4 so if anyone could point me in the right direction itd be greatly appreciated! also the cam is a tsp228r on a 112 lsa

I shifted my old H/C/I 4.8 at 7k all day long. On the dyno it quit making power at 6600 so i figured 7k was good

 

if ya dont mind me asking what cam were you running in it? and with the 228r do you think 7k would probably be a perfect point for it? also whatd that thing run in the 1/4?
