If your wanting to put a gen 3 LS to a turbo 400 and want to do it right. Then this is the way to go. Best bang for the buck. Had to wait almost a week but I'm glad I did. Great job guys for making this

Edit….. oops. Turns out my 5.3 had a 4l80 bolted to it previously…. That’s why they’re the same.Bought this for my lm7 5.3 to 4L80 swap. The specs on this flexplate are identical to my stock flexplate. Not sure if I got sent the wrong flexplate or what. Measured the snouts with a dial caliper and there is no difference than the stock one….
