Can someone tell me how long the negative battery cable should be for a 70 Big-block car? Also, should it have the small ground wire on it?

I believe it may depend whether you have a top post or side post but roughly 22". The grounding end of the cable is also different depending on which battery.

Both use a grounding wire to the fender.

The best (and only) information I was able to dig up was in Paddock's catalog. They list an AC Delco negative cable for 70 BB w/HD battery 25".
