Following is a post I made on a similar subject back in 2008. Of course, you'll upset all the Mopar purists that have to have their cars be 100% Mopar.
I haven't pulled the trigger on this yet due to a couple of economic setbacks along the way, but still thinking really hard about it when the funds are available.
Contact Art Carr directly at California Performance Transmissions (
www.cpttransmission.com or toll free 800-278-2277), Huntington Beach, SoCal. He's been building great transmissions for many years.
BTW, you're also going to need to rig up a TV cable to use the 200-4R. Art's got all the heavy-duty parts to build you a tranny to live behind your 408 stroker.
"I've been thinking about a 200-4R behind a 360 magnum crate motor in a '69 Dart for the past week or so. Talked to several tranny companies about it and finally contacted Art Carr at California Performance Transmissions last week. He estimates total cost including converter and installation at about $3300. This does not include a new 8" longer driveshaft since the 200-4R is 8" shorter than a 727. It's also lighter and doesn't have as much HP loss through the transmission. The gear ratios are better than the 727 and it does not require trans tunnel surgery to fit. Art says he has a customer in PA with one behind a 406 stroker that runs 11.80s and still pulls down 25 mpg on the freeway.
Somebody tell me something bad about this setup......"
