Wow, sorry, it seemed like there was some confusion from other folks. Sorry if I offended you guys. It took me some time to understand that "vortec" didn't mean gen III/IV for truck engines and that the 5.7 was actually a gen I.
I'm not offended. A year ago when I was researching this swap I spent countless hours trying to determine the difference, and even this fall when I had the issue with the flywheel I spent some time and no one here seemed to know. Everyone said ask Downey, and I did, and never got a straight answer from that avenue. Now that I had the issue and figured it out, everyone seems to know the difference.

I used to have a great image showing the dimensional differences between the two generations, if I find it again I'll post it up here.
