Normally you set your piston below the deck because of stretch. For the street. I would be using Carrillo rods. Have used them before in my 572ci big block Mopar.

That's why nobody uses aluminum rods on the street. They have a limited life and require maintenance and replacement. Why do folks over 1200-1300whp use them on a GTR? To prolong the life of the crank and rod bearings. The V6 design is hard on cranks. Why the guy above didn't get a Bryant crank is beyond me. They will break above 1200whp. When you get above 200hp per cylinder is the problem area. RealStreet did a video on it.
