Hi Dave,
The one thing that I would be hesitant about is the rear diff ratio in the Ricardo. It is nothing close to the ZF transaxle -- if you want to distill it down to the main issue if you have no trouble with mods, then this is it, IMHO. The Ford GT gets around that by brute power; and there is a modification to the Ricardo Ford GT transaxle -- but it is expensive.
I guess it all depends what you are going to do with your car -- I wish you all the best on getting it done.
