A quick search of Corvette Central's on-line parts listing shows part number 172105


Black, positive = 18 inches
Brown, negative = 24 inches

If you re making custom battery cable consider using larger sized wire say 1/0 or 2/0 with HD ends & terminal.

2/0 is waaay more than you need for a stock length cable on a small block. If you are into overkill go for it. I don't think you're gonna gain much.

IMHO you would be better served with stock 4 gauge cables and running an additional ground from a bell housing bolt to a battery box to frame mounting bolt.

Agree that 2/0 is way oversized for stock length cables. I used 2/0 cables when I relocated the battery to the trunk area in my 1969 AMX due to the very long positive cable length. Even then 2/0 was oversized....but I wasn't about to take any chances. For installation in a typical car, I think 2/0 gage will handle up to 400 amps intermittant starter current with essentially zero voltage loss.

If you use the thick cable, get welding cable with the ultra-fine copper strands, as it is more flexible. I also brazed/soldered the end connections on the cables...but doing this causes the final 2 inches or so of the connection area to become stiff. You need to determine what is best in your case.

Sorry, couldn't help myself, you didn't say 'correct' or 'stock'. I ran 1 gauge cable when I installed my battery in the storage compartment on my 66, but that's a long run, I never had much voltage loss with those big guys....K

1/0 or 2/0 wire is probably overkill but there is no downside to using it except for about $10 extra for materials. In my case before changing over to thicker cable the turn signal would not flash @ idle unless I rev ed the engine. It will now.
