You can use any LS style block (iron or aluminum), aftermarket or GM, from 1997-whenever...... and absolutely nothing will change in your ECU or Emmissions. Only going Gen3 to Gen4 has a couple extremely simple sensor changes like CAM and Knock sensors, they sell a cheap wiring harness for that issue, which is what I bought for my new engine.

My local builder is about to assemble an all new 370ci with forged rods and pistons for boost if you're in the market.
So that Corvette PCM is 58x Gen IV stuff, keep that in mind.
Block wise, yea they are the same just where the sensors are and some have the DOD stuff where others don't.

🤷♂️ lol…. Should I do a valley cover block off plate as Im going to mount the knock sensors onto the block… I’m thinking I’m going to have to run a catch can for the pcv system if I do this any suggestions?
