Description:

Selling s rare find. This is a never run, Gen 3 L33 aluminum 5.3 block. Was assembled, but then disassembled and stored in a back room at a dealership parts dept.  I had to bore it .020/.5mm over as it had a little rust in the bores. I can bore this to std LS1 bore if someone wants a "new" LS1 for their Z28 or Vette for an additional fee. As is with all the covers/bolts, $850+shipping and I can ship it FedEx ground in a crate to keep costs low. If you have any questions, DM me.
