Yes, it should. I use a rebuilt 70A Mustang unit with external voltage regulater. I use the largest Spal fan I could fit in there. Even with the brights on, I don't get a voltage drop. Except at idle. Then you'll see the voltmeter drops just a smidgen. But once the rpm's are back to 1,000+, there's no issue.
