Question Flexplate question 4L80E
So I'm starting my M6-A4 swap. My question is which flexplate do I need?
LS1 , 4L80E, 9.5" converter

I have no idea. A regular 4L80E flexplate won't work.

Depends on what converter you are using... Do you know what front cover it has?

That appears to have the LS pilot and is multiple bolt pattern. So you could use the 4L80 setup with the spacer. Or you can use a 4L60 dished type. Do you actually have the converter yet, or is that just from the web? I need you to measure the pilot to pad distance.

I don't have it yet. This is the one I was thinking of getting though.

I contacted them asked for the measurement or recommendationd on a flexplate and the response I got was "Just a standard LS flexplate is all you need." Nothing else, just that.

So from that I should assume a flexplate for a 4L60E would work?

They sent me another email and said a flexplate for an 80E is what I need. All the ones I've seen so far for the 80E are for an 11" converter.

I know jack **** about automatics.

That cover appears to work with either a 4l60E or 4L80E flexplate setup (assuming it has the longer 4L60E pilot).

Hughes has a SFI approved flexplate. Looks flat though, so I would need a spacer correct?
