Which flexplate? I'm doint a 5.3 conversion into my Blazer Xtreme and I am using a 06 5.3 litre engine and a 04 4l80e trans with a aftermarket converter that came with the trans. My question is which flexplate do I use the 5.3 or the flexplate that came with the 4l80e.
Thanks.
Thanks.

Correct, it will either has the LS bolt pattern and use the 5.3 flexplate or the 4L80 bolt pattern and use the 80 flexplate. Also need to make sure the pilot of the converter is long enough to reach the crank. If you use the 80 flexplate, it will probably need a spacer between it and the crank to get proper starter alignment and converter pull back.

I was looking up the part# for the flexplate/spacer/bolt kit for you (if you end up needing it) and ran across this great info:
