I've had both tranny's with a 3:46 rear gear. Go with the 600 with the higher first gear. You have options for the 5th gear but I chose the .82 since I do very little highway driving. Also, it just doesn't seem right running 1800 rpms at 70mph or whatever. The Cobra needs to talk to the vehicles as it passes by not sound like it is idling! The 500 first gear is very short. Just my opinion.
