That is a link to the ebay auction for the one I was talking about. Price seemed too good to be true for a trans with converter that would stand up to 700 hp. Don't worry, I'm not ready to click the "buy it now", I'm just shopping around at this point. Is he listing the right parts and it is just a question of whether they are actually in there or not, or his parts list missing something? Or is he using not good parts?
The guy from the ebay advertisement (Lou) called me this morning to talk about my application, as soon as he heard it, he turned tail and ran on going the 700R4 route, he instead thinks I should upgrade to the 4l80e, which is basically a th400 with an overdrive...... its the 3rd transmission speciality company that turned tail and ran with my application. Most want me to go to a th350 or th400 if I can live without the OD.... but I'm not geared or set-up for that right now and have no intention of changing anything else right now. What scares them is the several hundred passes per year of racing.
If you notice, on that ebay ad, they say on their website, (700 hp with radials).... in otherwords, if you don't hook it up, you'll be fine.
You are at the realistic limit of what a 700 can be built to take, and anyone that is selling one with a warrantee attached will be nervous. I was lucky, and never had to warrantee one. Too many variables. I think you will have your best luck with a local guy who will use a select set of overhaul and upgrade parts. Every builder has their recipes for success.
You really think so ? My engine build is very mild....436 sbc with a hyd roller cam, motor will not see the north side of 6200 rpm..... I'm estimating 540-580 HP...... and only around 520-540 peak ftlbs.
As a note, my last transmission "literally" lasted approxmiately 1000 passes, 11 seconds at a time, 1.5x 60 fts, and saw over 50k street miles on top of that. That transmission was simply a rebuilt bone stock 90 700R4.... I don't know what it came out of it. The guy who built it, built them for a living, and he knew my application and was confident it would last for years.... and it did. Never failed.... I'm sorry its gone. That old motor was a little under 450 HP, but did have close to 500 ftlbs of torque considering it was a Superram 383 motor..... my point, all I am doing is adding 20-40 ftlbs of torque and another 100 or so HP..... I would think something could be built for it.... but maybe not, I dunno.
I thought you were shooting for mid to low 10's. Your goals are reasonable (imho) for a 700r4. They hold up well until the 60' times drop well into the 1.4 range.
