throttle valve cable geometry

Yes it would take a little more work, and you can overcome any gearing issues with a lower rear gear ratio. The NAG1 trans might not be the budget swap, but it was behind the motor from the factory(unless the motor came from a truck) and is a damn good unit ! My buddy has a '67 Barracuda with a full 5.7L swap and is in the process of building a '72 scamp with a complete 6.4L / 6spd from a 2012 SRT challenger ...

I never said there was anything wrong with the NAG1, I said it wasn't right for my application. I don't personally think it's the best transmission for swap applications, but yes, it can be made to work. Just like any other transmission can be made to work, it's all in what you're trying to accomplish. Firstly, I needed something very compact, the NAG1 just didn't fit the bill, making any other advantage irrelevant.
