I want to install a big battery 1000 CCA in my 80. My buddy an old school mech tells me I will be over loading my electrical system. Electrically the 80 is stock I do have a set of 100 watt lights extra but thats it. The extra battery CCA is for that warm fuzzzy feeling . What say MUD

If your buddy was right then lot of the 80s on this board would have fried their electronics! Find a battery with a high reserve capacity if possible.
Go for it. The Diehard Platinum is the cat's meow these days.

In my understanding, it doesn't matter how big of a battery you have. It is the load that determines the draw, not the capacity of the battery.
In my case I'm running two matched Optima D31A batteries in parallel. CA 1125 and CCA 900 per battery yielding CA 2250 and CCA 1800 in my setup. No issues (YMMV). I also have a pair of 300AMP slow blow marine fuses, 1 per battery. It is in the dual battery FAQ if you have more interest.
Back to this question. Regardless of how much battery you have sitting in the box, the current going through the wires will be dictated by the draw from the device on the other end as pulled through the fuse blocks and fusible links. If the device calls for more power than the fuses can handle, they pop. It has nothing to do with the size of the battery.
IMHO YMMV I am not a mechanic.

I run an Odessey PC1700MJT in my 80. Other than having a custom battery tray built, it's a direct fit. I am a big believer in a single battery system for simplicity. No issues, runs my M12K without complaint.

I think I want to get away from a gel battery. i have one now and it is weak in just 2 years,. the desert heat took the Elvis out of it...

I believe that there's a big difference from the Odyssey/Die Hard vs the Optima (crap) batteries these days. You'll want to read up on the Odyssey site to get a better explanation. I had lead acid (wet) batteries and loved them just fine. It's the outgassing and the acid eating of the metal surrounding the battery that made me switch.
