I am also using the 65 3.09 box, and with the 2.94 gears combined with the lightweight flywheel I do get a little surge in 1st idling along. This may be able to be tuned out to some degree, like I said I think 3.23 will be ideal. I can say that mid way through first, and all through second gear it will incinerate the street tires with ease even with the 2.94 gears. Highway speed passing puts a large smile on ones face!!
