The 2004r is roughly the same package as a TH350. It's more expensive to build than a 700r4 but it can be built to take a beating.
Oh, ah, interesting. So they took the TH350, added an OD (and lockup converter?) and called it the TH200r4. So it's identical to the TH350 otherwise? Is it the same length, so it can be used with the factory driveshaft? I thought the TH200r4 was a weaker tannie than the TH350 because of the 200 number. But the 350 stands for taking up to 350 ft-lbs of torque, while the 400 is for 400 ft-lbs (although we know both can handle more than that even in stock configuration). That should be plenty for a naturally aspired 250 or even 292 inline?
