Look up this part number in any search engine:

Apt z270 flexplate

Its a brand new 6.0 flat flexplate, crank spacer, and bolts for around $50-$65. Much cheaper than using the over priced gm spacer and bolts with a curved ls1 or 5.3 flexplate! It allows for the use of a 11.5" th400 converter bolt circle, not the small th350 10.75 converter bolt circle that requires ovaling holes with a curved flex plate.

"Its a brand new 6.0 flat flexplate"

does it work on a 5.3 with a t400?

yes, it will fit any LS engine. i say it is a 6.0 flex plate because they the early 6.0s came with the spacer installed on the flex plate and a 4L80E transmission which mimics a th400. The ls1 and 5.3 engines come equipped with a curved flex plate and a 4L60E transmission.

you can use the GM spacer with your existing 5.3 or ls1 curved flex plate but you need to oblong the bolt holes and run a th350 10.75 bolt circle torque converter.

6.0 flex plate installed =
spacer, flex plate, torque converter

5.3/ls1 curved flex plate =
flex plate, spacer, converter


make sense?

Not to be rude either but did you even read my original post?

This post isnt selling anything. It just a listed part number for a conversion flex plate. Notice i didnt link the item to any vendor.

What is wrong with people helping out on this forum? I searched high and low looking for th400 swap info. I found this on a random page and thought i would share. If its offensive please remove it.

He's right.
Using a curved FP w spacer will cause starter and FP alignment issues. And possible tq converter issues.
The flat plate w spacer is best solution. On the cheap. if do not need sfi plate
