As I understand it, Fuzzy’s Vodka was quite keen on the idea of having their team up front more often ;-)
Carpenter didn’t come from a road racing background (USAC dirt track ovals, to be exact) so I don’t think there’ll be that much data for Conway to work with on his appearances. Unlike Dale Coyne Racing, he won’t have a strong teammate to exchange information with, so I wouldn’t expect a repeat of the Detroit 2013 performance.
In a surprise move, Andretti Autosport have announced the return of Franck Montagny to their Indycar team for the Indianapolis Grand Prix. He previously made one Indycar start with Andretti at Sonoma in the 2009 season.
Speaking of Brazilians, from the Barber entry lists it looks like Nicolas Costa has a full-time Pro Mazda seat. He did very well last year in his select appearances, after winning the Formula Abarth title in 2012.
Sage Karam is apparently being entered for the Indy 500 with Ganassi, although I can’t read the full report in the Indy Star (subscription is required).
