I wouldn't use aluminum rods in a street motor. Only in a drag motor. They have a limited service life because of definite metal fatigue life. In a drag motor. You normal tear it down at least once during the season to inspect everything inside. That includes measuring rod stretch. With using aluminum rods. You have to watch your deck height. 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.
