I have #6-3 Alum Wiring that was wired DIRECTLY to an 30 year old
JennAir Downdraft Range, which I'm now replacing. The circuit is on two
ganged 50a breakers. I'm going to put in a 3 prong outlet into the
wall. The wire has 2 black wires, one with a red stripe, the other
black wire with no stripe, and what looks like a bare ground wire. The
directions on the outlet say to wire the "hot wires" to the two angled
connections and the neutral to the "straight" connection. When I
started this I noticed the "straight" connection has the word "neutral"
embedded on the back of the connector.

Am I correct to assume that the black wire without the stripe is
"neutral", the black wire with the red stripe is "hot" and the bare
wire is ground? If that's right, then which what do I do with the
"ground" wire?

Thanks
Jeff C

p.s. I know what assume means and someone's going to say I should leave
this up to a qualified electrician, but sometimes money is short and so
is time, so please bear with me.
