8.1 Vortec Does anybody have any advice on this motor? I have a chance to get one of these but I don't know nothing about this motor. I'd like to upgrade 69 Camaro to an LS motor but I was thinking of an LS1 or 2
I have it in my 12 ton motorhome. It is a beast. Doesn't take many of the big block parts though. Check out these guys, they have some great parts for the motor but you better have a drive train that can handle the torque

Raylar is over priced and overrated. You can get off the shelf pistons and rods from Summit or Jegs, a custom cam, clean up the factory heads and intake or buy the Dart setup, but definitely dont just give your money away to Raylar.

The pistons will also need to be replaced to go over .530 lift. I would recommend going forged, or you'll be breaking them right at the ring land. Here's a user who picked up generic aftermarket replacements and did just that:
You'll need to replace your rods if you're going over 550hp. This won't be possible with stock iron heads unless you're adding boost.
The factory intake requires a great deal of internal modification to flow air. You can also run the dart carb / efi holly plate style manifold. Both work great and will support enough air to make 600hp NA.
We're here to help! If you've got questions on the 8.1L, we've got answers.
