trans king is also supposed to be really good. my th350 was built by trans pro with mostly coan internals, but be sure to get a hardened input shaft and 36 element sprag and the drum lightened for best results. i've also got torrington bearings throughout. expect to pay a little more than you would for a typically built th400, both with rmvb & brake, but less overall weight and more importantly less rotating mass which equals more rwhp!
