These are brand new boost pistons still in the box. The lunati part # is LSBR512S3. The specs are -13cc 1.23x4.030. I am selling them for $550. I paid $650 Pics of pistons and the original receipt are available upon request. These are pefect for an Iron block boost build.

 

What size stroke & rod length?

 

I think that it woul depend on the crank/ rod combo you choose. I was going to use 6.125" rods, never purchased the crank

I meant what stroke and rod length were these ordered for. A .030 over 6.0, a stroker, or what.

 

honestly I am not sure. I had purchased the lunati billet rods and lunati forged pistons at the same time through summit and just planned on getting the crank later when I had more money to spend. You would have to call lunati (1-662-892-1500)and ask them what combo you can do with them depending on what parts you already have.

 

Lethal performance says they are for a 4.00" stroke, 6.125" rod, and a 4.030" bore.
