you dont need a new flexplate, just convertor. Texas-speed.com has a TCI 3500 for LS1 th-350 swaps for about $500. Works with the stock flexplate and TH-350 input shaft.

I'm using a TCI Dual Pattern Flexplate, better in the long run. ATI 4000 stall (came with the trans). If you dont get a LS1 TH350 specific TC than you either need the flexplate, or a spacer. Also, dont forget the shifter, crossmember (with or w/o TA mount) and for speedo hookup, I recommend getting a 9" tailshaft from Rossler with the VSS Bung welded in, makes for easy swap. Stock DS will work, but is about 1-1.5" short for optimal length. GL
