Will Keith Black forged pistons for a first gen 350 work in my 350LT1?
I have the opportunity to buy a set of these for a good price, and was wondering if the LT1 uses different pistons that the first gen 350's.
Also, how are these blocks for cylinder wear, as these pistons are standard. Engine has 122000 miles. all stock.

Measure the block with a good dial bore gauge before buying the pistons.
most bottom end components for a Gen1 350 SBC will fit inside the LT1. Keep in mind the 1-pc vs 2-pc rear main seal though.

maybe not, I've seen pictures of engines with more miles than that which still had the factory cross-hatch visible.
And technically, a "re-bore" is a very rough cut. What you really mean is a fresh hone. If the cylinders are all straight and round, then a fresh hone might be all that is needed.

Well, when I said 'rebore' I ***umed that the honing was understood.
Ultimately you need to fit the pistons to the bores. If the factory bores are tapered or out of round then you need a rebore (and a cylinder hone). And in damn near every stock motor I ever tore down and took gauges to wasn't straight and square... If you're going to rebuild, it doesn't take much more to do it right, and a square round piston hole (round when heads are bolted on, hone with a torque plate!) is really, really cheap power.
