[DeTomaso] Minimum Battery Size?

[Curt Hall]

Now I have NO room to talk, but If your just looking to save about 10 pounds weight why not just take your shoes off and lose some weight! Baw ah ah ah  If its about a hard to start car that's different.
  Sorry I could help myself!

  How much is enough? In the ideal situation you twist the key, the engine
kicks over, and the alternator starts doing its thing. No problem. In the
real world where the car as been sitting a little while and the garage gets
cold at night, the battery has drained down a bit, the mechanical pump has
to turn a while to refill the carb, and the engine takes a while to creak to
life.

I run gel batteries in all my vehicles. They cost more upfront, but they
last longer, can be mounted in any position, don't outgas hydrogen, and
don't spill acid in a wreck. 

In my Pantera I have a blue top (marine) Optima 1000 CCA. I don't know what
it weighs.

Jack,
I just went out and weighed my battery, 48 pounds! No wonder my car
started so easy, I'll bet that thing could start a semi! I got a report
back from a guy using the Odyssey PC925 with 380 CCA, he reports no problem
starting his car. I think Bill Wright is using the same battery in his
Superformance GT40 sporting an all aluminum Roush 427 with 10 or 10.25:1
CR? The PC925 weighs just 26 pounds! Jack, I think I just found you an
easy way to shed 9 pounds! I see the PC 680 with 220 CCA only weighs 15.4
lbs! That would be way cool if it would do the job. I've been thinking
about installing the MSD cockpit adjustable timing control. Perhaps by
backing the timing off at start up, I could get away with a very small
battery? I'm thinking that with my new aluminum heads, the smaller battery
and a full tank of gas, I might just weigh in at less than 3000 lbs! 

Thanks Jack,
Art

Art,, I've run a 1000-amp battery and currently, a 735-amp unit. The first
weighed 48 lbs, the 2nd only 35- both 'Kirkland' brand from my local Costco.
735 is enough amperage to spin a smoking-hot engine at 10-1/2:1 compression
with ease, or to start the engine when stone-cold. 
Remember if you have a dropped battery, the absolute max width battery you
can use is 7-3/8" since thats about all the wider the hole in the front
trunk floor can be enlarged. If you still use the std battery mount, about
any size will work as long as the negative terminal is covered so the hood
doesn't touch. FWIW- J DeRyke
