That is more duration than most run on a 5.3, you will need a pretty loose converter.

I just don't want any PTV issues, it'll be a 3500 conveter, and N20.

I'm not sure exactly what you can get away with for PTV clearance, the +4 should help right?

in my opinion, its a lot of cam for the 5.3, try and keep it 220ish duration at most, trucks need torque..again just my opinion

ptv will need to be checked, but with the small valves, should be fine
