How would one know if a 70 Charger HEMI would have come with power steering? It's a 4 speed 4.10 car, power disc.

By looking at the ORIGINAL broadcast sheet or dealer invoice or the original window sticker.

I just sold a 70 V code (440 Six barrel) Road Runner,that was a 4.10 super track pack car. That car had manual steering,but because of the track pack option,it had power disc brakes. It sounds like the Charger you are talking about may have been ordered like my Road Runner was.

I'm guessing there's no gear box or steering column? If there's no broadcast sheet or any other forensics, it'll be hard to know...

If you have the original steering column it's a different length - shorter for power steering. If you are trying to determine if the box is correct, an origanal hemi PS box will have a 90 degree fitting for the pressure line.

In absence of paper documentation, dual groove crank pulley might be a good indicator. In changing a Hemi to manual steering, most would not take the time to track down a relatvely hard to find Hemi single grrove pulley.
