Yank Torque Converter

I was going to just run the stock 4L80E torque converter. Knowing that my supercharger starts to build it’s power at the 3000 rpm range, when I came across a SC3000 Yank torque converter, I bought it.

A 3000 stall torque converter seems like it would be way to tall for street use. Everything I’ve read says that prochargers love high stalls though. Some folks even run a 3600 rpm stall on the street!

Here’s a link to my torque converter on Yanks site.

Here are some pics of my Yank torque converter. As you can see, it looks brand new! That’s because the seller shipped it off and had it rebuild and then immediately shipped it to me. He never even opened the box!

Yank it and get it off quicker!

Here’s the Yank next to a stock 4L80E converter.

My torque converter is actually for a 5.3L. You see, the 5.3L has a 3 bolt flexplate and the 6.0L has a 6 bolt flexplate. When I bought my 4L80E I was figuring I would have to buy the 6 bolt flex plate and appropriate spacer. Luckily, my torque converter is a “conversion” one. 3 bolt pattern, 80E splines.

So why does it have 6 bolt holes? Good question. I thought for a minute and asked around. I was wondering if Yank accidentally sent the wrong one out or something. Well, it turns out, it has a dual bolt pattern. LS1/LT1
