Oil has gotten too expensive to let it just run out on the ground (I hear it's not too good for the envirnonment either) and the stuff is running out of every seal and gasket on my S10.  I need to pull it out and reseal it . . .  so I'm thinking I might as well go ahead and rebuild it.  Has anyone ever rebuilt a 2.8 V6 Chevy?  Anything I need to know before I start?

I've rebuilt small block Chevys before, but it's been about 30 years since the last one. This thing kind'a looks like a 283 with 2 cylinders missing, so I think I can handle it, but I'd appreciate any advice before I start.  I've got to get something else running before I start on it, so it'll be a few weeks before I start on it.
