Battery cable

[OldTimer]

Old thread but relevant so I'm gonna use it bc most of the links are still valid. I'm thinking about building some new battery cables for the 69 BBC Camaro. Battery is in stock location and it's a top connector type.

Couple of questions; first, I think the Positive (+) side is about 48" and the Negative (-) is about 30" am I correct? And the wire gauge is 4/0 but some folks switch to 2/0 which I'm considering. So 2/0 is thicker, stiffer, and will have less current drop than the 4/0, but are there more flexible 2/0 gauge wires out there? I only need one end crimped (Solenoid end a& Engine block Gnd) as I have a set of battery terminals with two Allen head crush slots per terminal. Is Marine cable not as stiff, or is Welding cable more pliable? The wire I'm looking at is tinned copper, would you fuse it with solder before inserting it into a terminal clamp?

I visited one of the links above (GenuineDealz) and they have two grades of 2/0 wire, the less expensive is just under $3 bucks a foot, the better quality is $6 bucks a foot. The difference is in the amperage rating, the cheaper one is rated 210 amps outside of engine spaces and 178 amps inside the engine space. The better quality isis 330 amps outside of engine spaces and 280 amps inside the engine space. I have a PowerMaster alternator that has a peak rating of 153 Amps at highway speeds, 100 amps at low speeds. I don't have a radio, no plans for a mega boom system either. Vintage Air and dual 12" fans. I'm going to use terminals with crush screw in two "ports" so only need one end to have a solenoid and ground eyelet. Suggestions?
