OD auto for a small block??
i spoke with Chris a short while ago about the 518. limited in valve body choices, if you look to http://smrtrans.tripod.com/smrtransmissionsintro/id5.html they have a reverse manual vb available. keep in mind, that if you run a od with a loose convertor you very well might have some issues with the convertor slipping on the road, spoke with several shops about it. one of which was http://www.ultimateconverter.com/home.html
probably will not be much of an issue, unless you are pushing some torque. you end up with a compromise, if you run a tight convertor with the od you might be lacking in stall, if you run a typical 9.5" convertor it does not contain enough fluid to not slip while cruising at 2200 rpm or so. an od simply takes a percentage of the gear out. 4.10 would become a 2.82 with the 518 .69 od. you would be trying to cruise at 2200 rpm, so cruising with a loose convertor will be a problem. and as mentioned you need to do a bit of surgery to get the 518 into the car. what it comes down to is if you want to run a loose convertor, and to run mid 11's with a small block, you probably will have to, you might want to look outside the Mopar box for a trans. the picture is of what it took to get a gm4l80e in a Dart. The Dart will have a 572 Hemi in it, with a crossram and efi from FastMan EFI on it. The 4l80 is a very stout unit, that takes very little in the way of upgrades to get it to live at 700-800 hp. you can run enough stall to keep your car happy at the strip yet be able to run a lockup convertor so you can drive it on the street. there is a few trans brakes available for it also. i have done a bit of research on this nighmare, and for me, this was pretty much the only solution. while you could also run a t-56 out of a viper, I wanted an automatic. the 4l80 is strong. you can get one with a manual valve body from http://www.jakesperformance.com/4L80E.html for $2100 that is claimed to live behind 750 hp. $500 or so for the QuickTime bellhousing, my buddy that owns a trans shop quoted me $1000 for a convertor. There is no reason why you cant run 10's and still get decent fuel mileage, if you are willing to step out of the era that our cars were built and into this decade. I have seen more than a few 5.0 Stangs that ran low 10's and still got close to 20 mpg on the freeway......
Disclaimer....the above is just my opinion. While I understand that the above will constitute the rape of my Mopar product, it is mine to do as I choose to. So if you are a purist and have an issue with what I am doing, why did you read this after the title told you not to?
