im looking to have a th400 built locally and wanted to know where to get the best parts and a trans brake for it to handle 750-800whp

also some people were talking about adding on a speedo gear possibly in the rear or a overdrive some how? anyone able to clue me in on that, ive done a search but theres just so much ive been trying to dig threw.

 

give me a call or pm as I have everything in stock from parts to complete units.
