    Resto-moding my 65 /6 cuda. Contemplating moving the battery to the trunk right side. (enclosed and outside vent battery case). Adding A/C, was delivered in Seattle but now in Ky. Going to improve the audio system, no ground shakers or extreme sound sytems. Other than that will remain stock. Would I, should I change the Group and Class rating of the battery? All advice and comments taken seriously. Thanks

    When the car is running, the alternator should be big enough to run the items you mention. The biggest load on the battery still remains starting the engine. With some of today's batteries, a group 24 size or even 27 should still be large enough for most cars, unless you have a huge CID BB or some'thin
