Hey John,
in my opinion do not waste your money with the keisler stuff...the t5 is not the strongest tranny out there, but i gurantee you that if you can find one in good condition that hasnt been abused and you actually know how to drive stick you will be fine (from what i know, your kick *** cuda only has street tires and the 4.10 gear will help the tranny live better too)...only thing i would avoid is powershifting, but then again your t5 may be fine with that (my buddy powershifts his t5 all day and no problems at all lol)...alot of guys are doing the swap with hyrdaulic stuff, and if you are cheap like me and have all the 4 speed clutch linkages, then you can use those with no problems with the quicktime bell...however there are some other things you need to know about the swap and if you want more info just pm me...ive done the whole swap except for one last thing...keep in mind though you will have to modify your tranny crossmember and tranny mount...in my opinion, if you have all the 4 speed linkage stuff, you can probably pull off the swap for not much more than 1k depending on where you get parts and for how much
like i said pm me if you want to know all the details about doing it this way....i have a t5 in mine for the same reason you want it in yours- low cruising rpms for a car you want to drive whereever you want
