Does any one know if there is any differnce between a non fuel injected 2.8 block and a injected one?

I spun a couple of berrings and I need to know if I could use any 2.8 chevy block to replace it?

 

I think the pre 85 blocks have smaller mains. and a 2 peice rear main seal?

 

The 2 piece seal was all I knew about.. thanks for the info 3.1!

The carb'd ones also had that fuel pump sticking out of the block. I know when a carb'd v8 guy gets an electric pump, they buy a block-off plate to cover the hole. I don't see why you couldn't do the same, and make one. Just use a normal pump's gasket on it.

Does anyone know the compression ratio or camshaft specs for 82-84 motors?

Also Knight, how do you know you've spun bearings? I'd like to be able to know if that happens to mine, but man I hope not!
