Don't know if the cam at the 6 degrees was worth anything. The blower makes up for a lot of little things that you would otherwise notice. It's not like you are the first guy to stick a huffer on a Hemi. I'm sure that there is legions of info on it and buku people that have a ton of experience. It really doesn't get any better in our hobby than what you're doing. Who doesn't want to play with BLOWN HEMI'S??? Hopefully someone with some knowledge will chime in here with their experience. Good luck with that thing!
