Man, I'm a double moron. One, because I just realized that the Chry to GM flexplate is for using a GM tranny with a Chry engine. The other reason......well here's the whole story. I ordered two converters from Edge, one for the 727, one for a Hemi truck. I opened the smaller box, thinking 9.5" converter and there was no starter ring so I jumped to conclusions. I emailed Edge and they called me back within minutes and we got everything sorted out. I was looking at the truck converter, which is actually the larger of the two. After opening the other box, I found the 727 converter with starter ring.
I can't speak for Edge's product yet, but I would recommend them just for their customer service and price. I got the two converters, the 727 being a custom 3200-3400, for just over $1000. Check them out at EdgeRacingConverters.com.
