The 220 is a great cam for the 4.8. I don't see alot of improvement with a custom grind.
Honestly I would start saving for 6.0 short block. Everything from your 4.8 will transfer over, you'll just have to invest in new gaskets.

You may want to go to a better header, those 2.5 collectors are hurting you some vs a 3". What size cai piping are you running?
Any more dope on this thing and it will explode ha ..... Just messing but I have hit it with 200 before lol
I just want to be faster n/a lol

You are asking about a different cam but what are you looking to spend for your next mod?
