look at comp LSr cams for the 4.8-5.3 i dont think they require flycutting but they're also some all out performer cams...

Just know the ms4 is great on ls1s just thought maybe the ms3 would work better since it has smaller cubes

Yea I wouldn't run that in an all out track car in a 4.8, just because you can overcam it which will make it perform like ****

I wouldnt even consider putting that cam in a 4.8, it will be slow as hell until 5k rpm.

you want a cam that will work best with your gears and tranny combo.fill out a cam request at compcams ,and you will under stand ever thing involved in picking the best cam.a small cam is funner then over caming a engine.the 54-455-11 cam mite be a safe cam.

we put a xer273hr in a 5.3 224/230 .581/.592 114lsa and it was on the verge of too big lol.. the heads are where you are gonna make your power not a huge camshaft.. a 6.0l is a better start for all motor.. i guess you could spray the hell out of that 4.8 tho haha.. maybe build a turbo for it..

More like a 5000 stall and 4:10's at least is what you will need for even that cam. Im doin a 232/234 in a 4.8 and i fully expect it to be a dog below 5k, boost will help though.

WAY too big for a 4.8L in a Camaro! I'd be focusing on the high-teens or low-220's intake duration (depending on bolt-ons, converter, etc)!

First thing u gotta do is raise the compression of the 4.8. By having the heads milled if u want to run long duration cams in a 4.8
Not necessary but helps improve acceleration response.

^^I'd agree and add along with more compression more cubic inches...even with 11:1 static compression, a high 230's intake duration camshaft is too big with 4.8L of displacement in about a 3500lb car.
