Circle D Specialties can definitely help you out. We have been in business since 1976 and our converters are in some of the worlds fastest LS1's. We strive to produce a quality product, not just quantity. We have a "+4C" that is rated at 4000 stall. Very efficient and good street manors. Please shoot me a PM for more detail on the car or give me a call.

I'd look into a Circle D converter.

If you want superior performance call FTI. 2 seperate classes were won at this weekends IHRA Sportsnationals in FL with FTI converters. We can help. We dont build cheap converters just the fastest. Check out our website FTI An SRLS billet converter would do the trick for you.Our website also has a build sheet that covers all the pertinent info needed when custom building a converter.Give me a call or shoot me a PM and we can discuss options.

FTI here.

Also was very happy with a 3600 Vigilante I had when the motor was stock.

I installed a Circle D 3500 stall TC in January. I have found it to be a really fine product. I can recommend Circle D. Very "driveable." I suppose you already know this, but you will need a tranny cooler. I also installed a Transgo shift kit based on info I got from this board. You can get the cooler and the shift kit from sponsors of this site.

Yank it and get off quicker. They are the best of the best quality wise, and have great customer service to back it up. I think a PT4000 Would be a good choice for you.

Anybody have the phone # for Yank?

02-11-2009, 04:16 PM
I have the Yank SS4000 and am very happy with my purchase. It dropped my ET down 1.1 sec from a stock converter and it has very good driving manners. Dave at Yank was very helpful and suggested this converter for my application. I called Vig as well and was more impressed with what Yank had to say.

That being said, if you get a vig, they do offer a free stall change, all you have to do is pull it out and send it to them. I wanted something that I didn't want to send out, so I did it once and am done with it. I have not had experience with Circle-D or FTI, so I cannot give any input. But I will tell you that a few of my friends went the cheaper route and purchased TCI converters. Well, lets just say those came out and were replaced with yanks very quickly.

Another note, my friend has a 4000 stall vig, and I can stall 500 RPM's higher with my yank than he can with his vig. He has a cam and I have a stock engine.

Circle D or Yank....

02-11-2009, 07:18 PM
I've run three Yanks and all have been awesome. I currently run the PT4400 and it's by far the wildest converter I've had. It hits hard off the line and the topend is absolutely insane. They build a quality product and customer service is great.

I'd also recommend Circle D based on what I've seen here at LS1Tech. Looks like they build a great converter and I've not seen a single negative post about them.....just lots of thrilled customers. Tough choice, but you'll be in great hands if you choose either of these builders.

Circle D all the way!!!

I run their 4C in our mid 11 second SS and their 8" race converter in our low 9 second SS. I have data logged many converters and I've seen the TC internals of some of the top converter builders out there and there are several good reasons why I will stick with Circle D for my converter needs.

Don't take short cuts in the torque converter department.

Whatever you do dont cheap out on the converter. My SS is on its 7th converter. After mucho research and time on the phone with various manufacturers the only two choices for me came down to FTI and circle D. I just finished my FTI install and the car feels great but its kinda tough to test a 4400 stall with snow and ice on the roads. Cant wait till the track opens in april. The smaller guys will take the time to build what you want not sell you an off the shelf one size fits all.

Of any of the top brands (Yank, Precision, Circle D, FTI) you will only be truly impressed with the converter if it is perfectly matched to the car and it's intended purpose. The more time they spend getting all the info from you (and the more accurate your answers) the better off you'll be.

If you had the wrong Circle D in the car that you bought used and swapped it for the correct TCI you would then think TCI rocks. (Until it takes out your tranny)

The convertor is most likely the key componet of how your combination works, These things are strange beasts and are not fully understood by the average racer or street enthusiest,TO GET IT RIGHT THE FIRST TIME YOU NEED AN EXPERT ON THE RIGHT COMBO FOR YOUR APPLICATION.
remember it costs just as much time and money to get it wrong as it does to get it right.

454 mag, have you really gone thru that many convertors.Are you a victim OF THE TRICK OF THE WEEK SYNDROME??????:ripped:

take care....

02-12-2009, 07:26 PM
Yes have reallly had that many in the car. Actually only had one go bad. it was the first "performance" converter I bought and I went cheap and got a fuddle. It lasted less than 5k miles and took out my trans. He did send me a new billet verter for a few more bucks but I was all done with him.
As you stated it is one of the most important pieces of how your car runs at the track and I keep refining it a little more each time. I race heads up on a .400 pro tree so the verter is the difference between winning and losing. Instead of hijacking this post I will start a new one with reviews and pros and cons.

A friend of mine has a Yank 3600 SS in his bolton Lt1, and it lays over badly on the big end. Its 60' is awesome at a 1.77 but it falls of right after that.
