Right. I have "about" a 95 Tremec T5 out of a Mustang I am gathering all the parts to put in Vixen, my 64 Valiant. I've compared all the ratios with the 903 3 speed and it should be one hell of an upgrade.
I mentioned a similar plan here
I don't have 5K to spend so i preferd to spend 0.5k
anyway lots of people pointed out the error of my ways and gently took the piss :)
