I just completed a trans swap in my 65 Chevelle. I just put in the rebuilt 230 I6 and had the powerglide behind it. I grew so tired of it that i went on Craigslist and found a Borg Warner T50 with a fresh rebuild for $250. It came with a running 194 which i promptly tore apart. It took 2 days and about $600, but the swap went off without a hitch and it runs like a champ!
