I believe they are the same. You can get a crank kit for like $200. Comes with polished & ground crank & properly sized bearings.

What stores are you lookint at? I stay away from auto zone & some the others. You might have better luck @ smaller stores that service small independant reapir shops.You could also look at a C-K chevy truck with 350 as well. Cranks should be the same.

They are not the same, You do need a LT1 crank shaft. The Cranks are balanced differently. I read somewhere that a 305 crank is closer in balance to the LT1. I do have one in a block sitting under my bench , I can check it if you are interested.

If you're still looking, I have a good set (with pistons still attached) from a 140K LT1 motor. Engine was still in good shape when I disassembled it (no spun bearings). I'd take 55 shipped for all 8 rods/pistons. :)

I have a set, but with any used rod, they will likely need to be resized. They walk around a bit with even regular usage. Also, if you are upgrading the rod bolts, you'll need to resize the rods anyway to do it right..

Look on fleabay, there is a shop with very good feedback that sells recon'd rods for $75... not a bad price. I considered them before I got a great price on some forged I-beams with ARP bolts already installed.

good crankshaft that needs polished or turned .010
I have one of those too, and the balance is different, LT1 rods and pistons are lighter than a regular 350, so the counterweights are a bit lighter as well.

Keep on the path of getting the stock parts if you are going to build a cheap motor. Hanging pistons and balancing an assembly can quickly eat up $$. I think I had $250 in machine work to hang pistons and balance the rotating assembly.

FHP-
I have a used LT-1 Crank and pistons with rods that I'm looking to move. I bought a used long block for a core, with 88K miles on it. How's $125. plus shipping?
