518...46RH
builds like a 727...with od in the tailhousing.
bolts right up to the small block.
get the year with three pin connector if you want lock-up tq, 2 pin just od.
Theres a 904 version too...just dont recall the #.
I have a 518 (ok, 3 of them:D) thats going behind a warm 360 in my Aspen wagon, 8.75 with 4.10's.
I'm going with the 46RH in my Valiant, but there is going to have to be some reworking of the T-bar/trans crossmember above the trans. With the 200r4, you just need to build a new crossmember and fold the pinchweld at the firewall.
