I was wondering if somebody can identify the fuel injectors in my 94 LT1 383. They have purple or violet tops depending on what one considers purple or violet. :-)

If these are stock, does anyone have a suggested upgrade for better HP?

they are not stock; stock injectors should be black

 

putting bigger injectors won't help your HP any in less your current injectors aren't filling the task of providing enough fuel as it is.
