What power/torque are you going to be running as i have been running (well loosely speaking) the bara box for 2 years and the big week point is the standard main shaft as i have smashed 2 to bits the second one split the gear box casing all the way round lol i have also broken the input shaft, very good gear box in low boost,but in high boost ever time i have lauched i have broken it . My current set up does produce very high talk low down. Bara is a cracking bloke to deal with, but there are limitations on any gear kit designed to go into the ford casing. This may not be the best thing to post ,as at present the box is being rebuilt and then i am selling it.
