Re: [Chrysler300] 413 pistons .060 over source?

[Sean Duggan <saduggan@xxxxxxxxxxxxx>]

Pins and rods on a 426 are the same as on a 413 or a 440 for that  
matter. Going .070 over or .060 over is maybe pushing it. The block  
would need to be sonic checked. Custom 413 pistons can be made that  
are oversized to any specification and any compression ratio. Check  
out http://www.rosspistons.com
