Can anyone tell me if I need the crank spacer or not? I already bought it after researching one thread but I have had other people tell me that it will bolt right up.

i'll say 99.9% yes both spacer and flat flywheel.

If it is an LQ4 it should have had a 4l80e behind it, so it will already have the spacer and flat flexplate.

usually but not allways, i had to be the guy that got the denali 6.0 with a 4l60e behind it. posed both problems flexplate/spacer and segment swap/pcm. both of which got solved promptly

here's the easy way to do it, more money but the flexplate is SFI approved.

Am I good?

nice. your good,although you may have to open up the converter bolt holes on the flywheel. don't panic though, the nose of the converter centers it. you'll be missing a bolt on the bellhousing block arrangement, but i suspect you know that. it would be a good idea to test fit the converter to the flywheel and the trans to the block. unless the trans is in the car. if it is at least test the converter to the flywheel. sweet you even got the exhaust flanges.

This is definitely one of the most asked questions. It could be a sticky.

The thing is, I couldnt find a straight answer in all the threads.

Someone should deinitely make a sticky.

The only hole i had to open up on my 4L80 flexplate is the smaller locating hole, dont get crazy with the drill though. The 6.0 ltr/4L80 flexplate has the bigger(T400) bolt circle so make sure you order a converter accordingly because the smaller(T350) bolt circle wont work.

IS that a wet paper towel in the passenger manifold? Only in Pearland.
