Yep, I agree, overall, especially for a street/performance engine the 5.7 rods are the better choice. If it is a serious race engine, then of course the 6.0 rods would be the better choice. With the stock length 5.565 rods, the rod angles become somewhat severe, and that severity is reduced with the 5.7, and even more so with the 6.0in rods. BUT, with the 6in rods (FOR A DAILY STREET ENGINE) you end up with a really short piston which will rock more in the cylinders. Also, with a 6.0in rod, the wrist pin hole is into the oil ring groove-----------------I DO NOT LIKE THAT AT ALL ON A STREET ENGINE!!!!!!!!!!! Therefore, I feel the 5.7in rod is the optimum choice for a street engine (SB400). Also, EVERY piston maker that I'm aware of now makes pistons for a SB400 with 5.7 rods, and today those pistons are just about as cheap as a 350 piston, especially hypereutectic pistons------------------which I really perfer for a street engine.
