[SCOBRAC]

First I would like to tell everyone here here how much I appreciate the useful information I have found in the Forum. Although this is my first post I have read many hundreds of posts and several thousand replies and I think there are some really great tips and information to be had here. And the price is right as well.

A very long story short. I just got my first Cobra from a guy with more money than sense and recently he lost what money he had. The car is Contemporary #3152. It is BRG with Wimbeldon stripes. It sports a 428CI FE powerplant, 8v med. rise with Holley 4160, 450CFM carbs. The guy I bought the car from told me it was built in 1988 by Don Borders of Southern California. Since 1992 the car has been neglected first by the owner and unfortunately, several "good" (at stealing?) mechanics. The car is outstanding overall but has a few very strange quirks I am trying to sort out. I have three questions really.. Here goes.

1). Does anyone know a decent resource for learning more about Contemporary's in general and / or what a Contemporary wiring diagram looks like.

2). My battery, 650 cca deep cycle, with #1 gauge cables and NO electrical accessories (amp meter, coil, regulator, and alternator are the only potential drains) will be completely dead after 48 hours if I leave the battery terminal hooked up and the ignition switch off (if the terminal is unhooked no discharge, obviously)
the alternator is a new three wire autolite with a white a yellow and blue wire. voltage at the alternator is 15.2, at the battery I get 13-14.5 at 2000 rpm.

I guess my though is that I need either a diode or resistor wire inline to the alternator and am wondering if Contemporary would have done this, or would that be up to the builder? Is it common for this to happen and I should just use an isolator switch? As I mentioned the former owner was no help and actually may never have had a working charging system as the vehicle has been driven fewer than 20k in fourteen years and not at all for the last four.

3). Any opinions on the carbs? a total of 900cfm but they are mechanical secondaries. I have no problem with Holley's having grown up on them. The V/E V. CFM seems right for a street car but I am wonrering if a vacuum secondary system would be more driveable and give smoother power delivery. Does anyone here use a med. rise Ford 8v with 600-750ish vacuum secondaries. Is 1200-1500 cfm too for a street car?

Thanks in advance. Sorry this post is so long..
