I bought a project suburban and have been going through it getting everything back as it should be. New interior, steering components, tires, hoses etc. Pretty much anything that was broken or a consumable/ wear item was replaced. The body was in great shape except for a damaged RF fender. It came with a nice salvage one which I have now installed. I thought I was through the worst of it and it was about ready for service and then the engine started knocking. I pulled it out and disassembled it. It was really a mess. All of the bearings were absolutely trashed and the #2 main spun. I took it to the machine shop and they confirmed that it's beyond repair. I have read some about strokers and other larger swaps on here. This site is a really great resource and the collective knowledge shared here is outstanding. I am a chevy guy but all of my previous experience is with small blocks and mostly carbed ones. I was hoping that by starting a thread I may get some helpful suggestions for things to consider while I go through getting it all back together again. So thanks in advance!
I placed an order for this engine:

I havent received any updates on shipping yet, but I am hoping it will actually be on the way soon. Since the truck obviously had a severe lack of maintenance over it's previous history I went ahead and pulled the transmission out today to get it rebuilt while everything is apart. If I didnt go ahead and do this, my luck dictates that within 1 month of getting the new engine operational the transmission would fail. I have learned to embrace the demons that haunt me and just go the extra mile to remove their opportunities to cause me grief whenever possible. The transfer case needs rebuilding anyhow because the clutches were smoked. The fluid was the nastiest smelling I have ever experienced. I am done with new vehicles and my goal for this one is to be as reliable as possible when I am done with it. I realize the stock intake is not ideal for maximizing the power potential this engine, but I would imagine the same statement could be made about the stock engine as well. From the reading I have done, it does seem to potentially help (or at least be adequate for?) the low end to mid range and this will coincide with my intended usage just fine. Blackbear performance told me that the injectors I have would not adequately support this engine and suggested that I get 2001-2002 GM LS1 injectors. Otherwise he said it he could tune for the larger engine with no problem. I am aware I will need to swap over my timing cover with the crank sensor and the crank reluctor. I have read about the harmonic balancer having clearance issues. Would this be resolved by swapping my old balancer onto the new engine? Comments on this would be appreciated.
