4.3 to 6.0 swap with 5 speed. Help!!!!!

[Timmer1]

Hi everyone, I'm new to the site. I have a 2000 Silverado 1500 with a 4.3 and a 5 speed. I have tore that all out to put in the 6.0, and ran into some problems. I tried bolting on my flywheel from the 4.3 to the 6.0 and the holes didn't line up. Everything else was exactly the same tho. Has anybody successfully did a 4.3 to 6.0 swap using the stock 5 speed transmission? I'm in need of a little guidance if any of you have. Otherwise, if I can't figure it out soon, I'll have to put the 4.3 back in, and I don't really want to do that. It's my daily driver and I don't have anything else to drive when my truck is tore apart. Thanks!

if not mistaken you'll need a flywheel from a 5.3 or 6.0 to make it work

My guess is that you will have to get a 6.0 flywheel, I don't think they have one for the 5.3
