I have read through numerous threads on this subject, but thought I would ask for advice since every build is different.

I am doing a frame off restoration on a 65 GTO. All of the wiring harnesses will be stock 65. The engine, as well as all of its mounting brackets, alternator straps, power steering, water pump, etc, is a 69 428.

What I am wondering is what size alternator I will need for my requirements and possible upgrades. I do not mind bypassing the external regulator if an internal regulator is better than an external. I have also seen where some have recommended the 12si. This is also not a problem as long as it will fit the 69 brackets without the need to modify.

This is what I have and my future plans for the car. It has a Mallory electronic ignition. It will be getting a Vintage Air Conditioning System. It will be getting electric windows. The radio is rated at 240 watts total, in the future I might add an amplifier. The one I am looking at is rated at 1200 watts, not sure what the actual power requirements are. It will not be used to drive anything huge like woofers, just two 6x9 Alpine speakers in the back and two 6 1/2 Alpine speakers up front. My intent is to drive the speakers more efficiently to make them clearer and not to make it loud, I like my hearing just fine. I also want the available power in case I have to upgrade to electric fans for the radiator. The ones I am looking at are rated from 12 to 50 amps peak draw. I have seen some that go as high as 80, but that is really over kill. It is more realistic for the 12 to 25 amp range, 50 at most. I really think the stock fan and shroud will keep this car cool since I am installing a Griffin two row 1 1/4" radiator and Evans pump, but I just want to have the ability in the alternator in case I need the electric fans.

I also know it is recommended to upgrade the power cable from the alternator to handle the increased power. Where can you get these and what is recommended? I do not see anything like that listed with our host or other sights like AMES and OPG.

Thanks for all of the help,
Dale
