Chrysler 426 CW -101 Keith Black intake

Hello,
I'm new to the forum and I'm hopping someone can give me an idea of the value of these 2 Chrysler 426 CW -101 Keith Black intake ,mfg by Sharp. Also the year that they will fit. Are they for fuel injection or do they take 8 carburators.
THANKS in advance for your time/help .
