What size injector for my application Let's say I go with MSD injectors. What size should I go with?
The car is basically street.
I was thinking 50 lbs hr. Would 72 lbs hr be overkill?

LOL @ 72 lbs for a head/cam car. 
You arent pushing 700HP man, lol.
Stockers will be maxed out with that cam.
Pick up a set of Ford SVO 42'lbers, they flow great and will leave you lots of room to work with. I and a lot of other run them in Head/Cam apps. You can pick them up for cheap too used, like around 200$.
