This is our version of the perfect LS flexplate. Billet aluminum, offset built in, CNC machined, every GM bolt pattern. No issues with the converter bolts rubbing the block like you might have on other models.

That one work as well, if the converter has the dual bolt pattern on it. THe Stamped Steel one only has the LT/350 Bolt Pattern. So if your converter has 2 holes per lug, then you should be good to go. How much HP are we talking?

I would go with the billet aluminum. The stamped steel one is SFI approved, but if you are over 750 I suggest the billet one. Peace of mind....
