Stalled cars are alot of fun. I Have the typical LS1 automatic set up, and I would say the converter is the #1 mod. I wont put anything other than a yank in my car. You get what you pay for. I 've had the SS3600 for 2 years and its worked flawlessly.

But get ready to do a good rebuild on the tranny if you have a hard hitting converter. those 2.5-2.7 STRs are pretty rough!
