Finally the 66 Dart is here!!

That rad you put in from the Audi is a sweet fit. If the fans are drawing to much power, why not try that rad (fit looks perfect) with an after- market electric fan for the beast. I had a 73 scamp (360 v8) that ran an electric fan, so I had put in an alternator from a dodge truck that was heavy duty rated (360 engine and 3/4 ton) and also had air conditioning to compensate for the current draw. It put out more amps and I never had a problem with it. Also helped with my after-market stereo system. I also had an old jeep I did the same thing to to run all my lights, winch and other accessories with success. Find out what the amps of the Audi alternator and try to match it close, maybe they have a system to boost the current to the fans when they are on...How's the blue beast at the track...next time you go to the track let me know, I'd like to see the beast run...
