Tranny Help
My truck originally had an inline 6 and th-350. I am putting in a 475 horse 383 and wanted some advice on wheather or not I should put in a B&M th-400 from Summit or just get the 350 beefed up from a local shop. Also I wanted to know if the 400 will only fit with a high hump cab.
Thanks in advance
Manny
