For a street car, remember that more stall = more heat, too, and heat is a killer of automatics. Not such a big deal on something light like a coupe, but nevertheless hi stall converters on the street can lead to some real heat issues. I'm with Mark on calling the companies who make the converters to get something right for your car. On the rare occasions I actually use an automatic transmission, I write down all my engine and car information, take it to my pal Jim--who builds automatics for a living, then Jim calls the converter company he uses out in Colorado and a week or so later here comes the converter I need!!!! On the drag cars, whole different animal then what works on the street, Roger and Rodney are both running Coan converters and glides now--and I still have my 5 speed with a Soft-Lok clutch--so whenever we're together we always have something to argue about, consistency vs. lots of gears to keep it in the power band!!!!!
