I've got a gen 3 5.3 block already vatted and checked by the machine shop. A balanced rotating assembly ready to build a ls1 out of an iron 5.3 block. Just have to bore the block ( I will have the block bored for you if the deal is right) compstar forged rods and manley forged pistons. Also have a stock 5.3 crank already balanced with the rods. I live in Lubbock texas and I am willing to ship at your own cost. The pistons and rods have less than 30 min of run time on them the previous block failed due to dammage done by the installer. I intended to build this engine for my truck but decided to go larger with my tax refund... I'm looking for a method injection kit for my 09 Silverado or enough cash to buy one myself.

 

Price required as per section guidelines.

 

If you part out i will take the rods for a fair price pmed ya
