i have the comp cam >>>224-228-581-588-114+4. i was planning on a 6.0 this year but having to owe over 6000 in taxes and a few things that have come up are going to negate that. this is the cam i dynoed with. i am wanting to go to a tr220 or comperable. a 224 would be good as well. let me know so i can pull this one out.
