A good friend of mine is considering installing a manual tranny into his '92 mustang mainly for street use, occasional drag race. He is currently running a 347 stroker putting out about 400hp with a Performance Automatic C4 and 373 gears. The car was originally an auto also. He is mainly looking at the T-5, Tremec TKO's, and Tremec six speeds. In the future he may add a power adder of some type, so it'd be nice if the tranny was strong enough for that too. What are everyones opinions on which tranny would be the best choice for the money? Also what all is involved in this swap other than adding the obvious pedals, etc.? Any other suggestions are also very welcome. What are the best places to buy these tranny's from? And finally, what should he expect to be able to sell his PA C4 for?
