4L60e + 450hp... ?

Aright, I know there have to be some LS1 people running automatics with a Vortech Supercharger. Who builds a hard 4L60e that will last a bit under supercharged abuse? How much will it cost to build such a tranny?

If you want to do this yourself?, go to http://www.pro-built.net/index.cfm?fuseaction=viewproduct&productid=48 If you need a transmission?, go to http://www.pro-built.net/index.cfm?fuseaction=viewproduct&productid=177 What year are you planning on using? Let me know if I can be of help?

Hey probuilt, it says 93-96.....so what about us 97 guys?

The 2 piece bellhousing/case units are very expensive core wise. So I have the customer send me their core, and I deduct the shipping charge from the price. Otherwise the price for these is the same.
