Anybody running a Comp cams 268?

Also, some guys just run the 6.1 cam same basic specs, but a little tamer idle and cruising. May help with the converter issue. I would think a tune would be necessary... I thing i got everything to do the swap from moparsupercenter.com they have the best prices on springs and stuff, and it says right with the springs what to order with it... They also have the 6.1 cams for way cheap...
