6 Inch Rod Vs Stock Lt1 Rods

ANY HP GAINS BY CHANGING THE STOCK LT1 RODS FOR 6 INCH RODS? IF SO, HOW MUCH?

You might want to try a "search"... this issue gets covered here regularly.

If all you did was change the rods (with new pistons to match) and kept eveything else the same, any performance difference would be negligible. A combo optimized for the longer rod may make a few more hp though.
