I read that you need a "special" flexplate and a 3/16 spacer to mate a smallblock trans to this engine. I recently read that a mopar flex plate and no spacer would work if you cut the mounting lugs on the convertor .070". If that is true, could I just run a .090" midplate and call it good? Would this combo allow me to use an off the shelf convertor with stock starter location?(no spacers or adapters)

Since your playing with a 727 I have no problems running a .090 mid plate with the normal conv nose.. if you go above .090 (like .125 I would suggest that you have the nose lengthened).... unless for some odd reason they have the flex farther into the back of the G3 block... but the trans is still in the same place as my R3 so you should be fine

If you run it that way, good luck. Cut the lugs down .070 (I believe it was me who told you that) and it'll be perfect or run a .090 midplate and you'll be fine.

I made a spacer. the lugs on the converter touched my flex plate and I didn't like it so I made a spacer for mine. At the time I couldn't get a good answer on this and I did what I felt I needed to do Gen 3 power 6.22@110, 9.85@135 Follow @g3hemiswap on instagram performance only racing, CRT, ultimate converter, superior design concepts, ThumperCarbs

I don't know. maybe the offset on the cheap one I got isn't right requiring a spacer Gen 3 power 6.22@110, 9.85@135 Follow @g3hemiswap on instagram performance only racing, CRT, ultimate converter, superior design concepts, ThumperCarbs
