Comparing manual trans options - variables other than gear ratios?

The guy says "other than gear ratios" and what's AJ give him a belly bait of? Good GAWD that guy loves to see his words in type.

All I can add is to reiterate that besides gear ratios, there's fit and finish. The best one of those, IMO is either the standard A833, or the A833 OD. Both will bolt slam in with factory parts and require cutting nothing. From there, you'll be cutting and fabbing. I'm getting ready to install a Ford world class T5 in Vixen, my 64 Valiant. I chose it for several reasons, and gear ratios was one, but I'll leave that out since that's how you asked. All of my other reasons are, it's plenty strong enough to hold up to a slant six, it's a VERY popular transmission, affordable and parts are readily available. Yes, it requires floor tunnel mods, but that's ok. I had Gill Welding make me a custom adapter plate that will bolt the T5 onto the original 64 slant six bellhousing, so that enables me to retain all of the stock clutch linkage and not have to fab anything other than the floor tunnel, floor tunnel hoop and cross member and also shorten a drive shaft. Easy peasy. There ARE stronger versions of the T5 if you decide to go that route. Oh one last thing I forgot. The T5 is a lot lighter than even the original A903 3 speed that's comin out. For whatever that's worth.
