" From: <mail@xxxxxxxxxxxx> " " I measured the T-4 in my Garage yesterday it is 24" from Bellhousing " face to tip of tailhousing where the output seal is pressed in. Same as " others I have seen measurements on. thanks! that confirms the impression that all t4/t5 are the same lentgh pretty much. " I've been thinking of this T-4 and possible uses for it. " Best one I've com up with so far would be for a drag/ road racer wanting " to build a light weight 4 speed. Stuff a top of the line gearset on a " world class main shaft mount it in a Ford World class T-5 main case then " add the T-4 Tailhousing and top cover shift assembly. " Your shifter would still fit the factory console in Concords, gremlins " Etc; And you'd have a stout 75 lb four speed! I think some of the gears " sets are rated at 500 plus horsepower and ft lbs torque for T-5s. Some " of the race T-5s are sold without fifth gear in place anyway. the strongest 'stock' ones are the ford svt, 330 ft-lbs. g-force makes super-strong internals which they claim are good for 600 hp, but that wouldn't take more than 330 ft-lbs if you're talking 10000 rpm... " You might have to mill off the end of the cluster though. I'm not sure " how that would work. hmmm... straightforward, with the right tools - carbide or diamond i'd expect. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
