170 or 225?

Ok. Went and actually bought the car today. It did in fact have a Holley carb. I know this does not necessarily denote it being a 225. Turns out it is a 225 though. The hose was about 3 inches long and the air filter cover had the “charger 225” sticker on it. Thanks for the help guys! I’ll post pics and the car story on a new thread.
