From the factory they are good for 250-300, but with billet internals they can be built to reliably handle 800-1000. Once you are into 4 digits and annual rebuild is likely though.
Exactly what I was searching for that Dart is built right! I'm building a (street) 426 Hemi for my '64 D100 and am needing a built transmission and finally found out about Art Carr's (California Performance Trans) 200-4Rs. Good to know that there are others out there capable of building this trans well. Would love to hear how yours has held up after a couple of years.
Mine has held up great so far. It doesn’t get driven as often as I’d like but when it is driven, I’m not always easy on it. The throttle valve cable is extremely important to keep adjusted properly FYI. If that’s not correct, won’t matter how well the trans is built. If you want a built trans with a warranty, look up extreme automatics. They have stage 1, 2, and 3 units up to 1000hp capable.
People get this confused because of the 700-R4. The 200 isn’t the same nomenclature. It is actually a 200-4R. People that say 200-R4, 200R4 are incorrect.
4500 stall currently which is less than the 5500 stall it used to have. Only thing I would change for this combo is getting rid of the lockup converter. Cam has too low of LSA for the low rpm and isn’t really smooth until about 3000 rpm and up. The high stall without the converter locked up does nicely soaking up routines from the cam cruising at 2500 rpm at around 80 mph
A lot depends on how expensive of components you use and how much labor you farm out. I did most of the fab work but all the conversion components added up. With my specific setup from shifter to driveshaft was around $4500. It could be done for much less but this was built to handle 10 second passes. An A-518 would be another option that could be simpler and less expensive possibly.
