i wana move the battery to the trunk, its in the way of my cone filter idea, and i'd rahter have like 10lbs in the trunk insted of up front, that V8 is enough wieght up there. So what all do i need to get/do?

Try summitracing.com or jegs.com for a battery relocation kit.

cool, thanks. 42 bucks isnt that bad.

Maybe now would be a perfect time to put in a Optima battery. I heard that even if they crack they don't leak. Might be nice to have that in the trunk.

Good idea with that Optima.. What IS the weight ratio on these cars? I mean from front to back?

thats a good question, one that i really wana know. And how muc do those optima batteries go for?

Optima, roughly $100. Educated guess 57/43 weight bias. Word of advise. Make sure the wire runing off the altanator to the positive post of the battery is at least 10 gaw wire. I had a charging problem with my 85 FW when I did that mod. If you buy the kit from Jegs you should be ok. I built mine from scratch so I had problems. Live and learn I guess.

A search turned up the following:
current model STS: 62/38
DTS: 61/39.
CTS: 52/48
'67 Eldorado: 58/42

I would imagine most FWD Caddy's being at least 60/40.

Hey Shaun,
Good to see you here ;)
The Optima is a great battery for specific applications. Also remember that the Optima can be mounted in any orientation (sideways, on-end, etc.). Also, cable routing is CRITICAL for safety as well as durability.
