LS Flexplate question

e vassar · 02-28-2024, 11:42 AM

I bought a ATI 915543 flexplate for my LS T350 only to find out it won't work because the LS crank is a little shorter out the back of the block.
So went with Jegs 601080C it has sort of a bell shape for the clearance. I do plan to go with a metric 200 at some point, so my question is..which flexplate works with the metric 200?
Thanks

That same Jegs plate will work with both TH350 and 200

The short crank LS engines need a pilot spacer to mate to the converter, or have your converter built to the LS length. Using a spacer allows the use of any typical aftermarket converter

Meziere FPS174 and FPS174A will allow you to use any standard Small block or BBC converter.
