Is the # 6290592 the right cable for the #Y55 battery?  Or is the #6290591 as shown on T60-A1 in the AIM? It is interesting that the Z/28 cables are shown in the HD battery section. It seems a bit confusing.

Yours would be for a Y55 battery, so the broadcast codes would be MF and BF. I'll let someone else confirm the #'s.

I replaced mine ten years ago - they were corroded internally.

The AIM shows the Z/28 cables under the T60 option. The XXXXX51 cable seems to be the one but the vendors say XXXXX52 is correct. It is weird that the Z/28 cables are shown uinder the T60 option, but which number is correct? Thanks.

The optional T60 HD battery cables (small block) part# for small block Pos 6290591BW, & Neg 6296756BH These were used in conjuction with the R69 70ah battery.

The Z28 came equipped prior 5/69 with Y55 top terminal battery. The two codes I have seen on broadcast sheets are MF(for pos cable and BF (for neg cable). I will dig up the part# and pics. Z28's built 5/69 and after came standard with Y77 battery and cables 6297684AS (pos cable) 7 6297651AV (neg cable).

Steve, page T60-A1 shows #6290591 for Z/28. The reporo catalogues show #6290592 for Z/28. I find it odd that Z/28 cables are in the T60 section at all. My experience with #6290592 is that they are very tight in length. The extra length of the #6290591 would fit better on the Y55 battery.

I can't believe I have thrown this hanging slider of a question. Grin

I went thru all the broadcast sheets that I have and all the Z's (20-30 of them) have a MF cable except one that has a BR cable on it. No other docs on that car, but I'd guess that car probably had T60.
Hey, if it fits, that's what matters...

BTW, the Z cables on the T60 page are only if the car has T60. 6290592 would have been the cable for the L6 and the base LF7/L14 motors with T60, per that page. Not to say it couldn't have other usages....

I do not see MF cables reproduced. The BR is the one most people say is corrrect. The BR  fits tight on the Y33 battery, though. Another thing with no definitive answer. What would Jerry M. use?

Gary I use the reproduction  BR cable on three of my Z28's and my cables do not fit snug at all. BTW I use factory fit cables. Have you checked the routing and length of the cable.
