Pilot Bearing already in auto LS1? I'm swaping a t56 onto an LS1 that was originally equiped with a 4l60e. My question is: does my Ls1 already have the proper pilot bearing, or do I need to remove something and put in something else. Any help would be appreciated thanks allot.

Even if there is one installed, I'd pull it and install a fresh one. Years of gunk accumulating in there guarantees it's not in optimal condition for use.

Nope, there is no pilot, I know bc I pulled my flexplate last night. Its a hollow cavity. Get you a pilot bearing and tap it in. The needle bearings go towards the crank.......I think

I'm squinting really hard, but I can't see your crank from TEH INTARWEBZ. You might have to, you know, crawl up under there and check.

I'm having trouble figuring out how you got that.
If you hit AutoZone, they have a great slide-hammer kit and puller you can borrow for free...if you find that your engine has a pilot bearing installed.
They also have a bearing race driver set that works great for properly installing the new pilot, definitely get it. Don't use a socket as some have suggested, you'll smoosh up the exterior surface of the new bearing. Use the driver and install the new bearing right.

but yea deff just get a new one....and if you cant get the old one out with a puller which didnt work for me cuz the jaws kept slipping out...pack it full of grease and put in something that just slides in the hole and hit it and keep packing it with grease. It was the easiest thing ive ever done.

I'd recommend against it. The LS1 crank is hollow, and using the grease ram trick usually pushes the plug out of place causing a big-time oil leak...right onto the clutch disc. Nice trick on Gen 1 and 2 engines, bad idea on Gen 3 and 4.
AutoZone loans a spiffy slide hammer puller set, and a slide hammer to go with it. Haven't found a pilot bearing/bushing yet that this sucker won't get out with minimal fuss.
