727 overhaul questions. Good valve body w/ trans brake

I will be dropping off my 727 for a rebuild within the next few weeks. I decided to spend the extra money and go with a trans brake. What company makes a good full manual valve body with a trans brake ? Any other tips would be great. Car is only gonna be making around 350 hp 450 max on spray. Also I am going from a 904. I know I will need a shorter driveshaft. Is there anything else needed to make the swap from a 904 to 727?. Thanks in advance and input is appreciated!

I would say....Tranzact of Indy...A&A Transmission...Cope Racing Transmission...ProTrans out in Palmdale Ca....

I currently have 4 of Tranzact Pro Brakes.....one is 24 yrs old...

Torque Converter for a 727 will be needed.

Build the 904. It will go a few tenths faster. Under 500hp no need for a 727.

I would recommend A&A transmission they have several options to chose from. I've been using their trans since 1993 awesome part.
