i had a 6.0l and a th400 with the correct converter to go up against a sfi flywheel. and i didn't have a spacers i know certain years need them because of the longer and shorter cranks. im going to be getting a 5.3l is there any years that would need this spacer?

The 1999-2000 6.0L's have the longer crank flange. The 5.3L never had the longer flange.

so as long as my 6.0l wasn't a 99 or 2000 the 5.3 should bolt right up then?

here is the set up i have now on the 6.0l. im going to be getting a 5.3l and i plan on using the TCI flywheel along with the same converter. will this all bolt up correctly?

That's the short crank flange 6.0l your good to go. Remove the dished 5.3L flex plate and run the flexplate you have it will all bolt together.

I got "peace of mind" by bolting it all up and checking for proper fit while it was on the ground where I could get to everything.

Looks like your flexplate has all the spacers built in.

That flexplate is, ummm, different... I'd mock it up for sure after seeing that.

why do you say that? i had this all together running on my 6.0l. im thinking about getting a 5.3l was just wondering if i needed anything different to make it work.

If you're talking to me... Your first post didn't say that it was a running setup, just that you "had it". Regardless, with use of non-stock parts, I always mock-fit everything first. Then when it goes in the car, it's there to stay.

i was just wondering why you think its different? im no pro just wondering. could of been wrong all together. got it from someone else along with other parts.

thats my fault for not wording that better. thank you for your time and help.

Google up some pix of a factory flexplate and the difference will be obvious.
