Twin charged 6.2 cam question..
Your tfs 255's flow ~360cfm @ .600", and ~380 @ .700", so you are going to want all the lift you can get. Flycut the pistons, if necessary. But you want to capitalize on that airflow.
As for actual cam specs...? Call any of the big cam guru vendors on this site... Cam motion, tick performance, mamo motorsports, texas speed, tooley racing, guerra group... to name a few.
Duration is what will cause issues
Like said above
Contact a sponsor that specs turbo cams and see what they reccomend
Better advice than youll get grom someone on here usually
