aluminum rods for the street?
aluminum rods for the street? I've been searching as to the feasability of Aluminum rods in my next motor build. Trying to keep down reciprocating weight is a key element to me, so save the "just go with a forged setup" comments.
It seems that the GRP and the Jaeger rods (can't find 'em anywhere) have a good rep, and are used in a lot of race builds. Now I have also read that the aluminum rods flex, and possibly distort more so they need frequent inspection which makes them unacceptable street components. Does that seem to be the consensus? couple more questions:
Anyone build a motor with aluminum rods that does street duty? Seems the LS7 titanium units are working out, but I know titanium has different properties. If you do have such a setup whose rods did you go with, and what specifications?
Many have said lightweight steel units function just as well, but I cannot seem to find sub 500g steel pistons. Anyone care to point some out to me that would work with a ls7 diameter piston?

Use to, aluminum rods had a very short life. They would stretch. Some people would just run them so many runs, and throw them away. Because of there mass, I am not sure if they was actaully any lighter. They was mostly used as a shock assorber on the big high HP cars. But I think they may have aluminum rods now that will last longer, and can be used on the street. If you could find some made out of 7075, that would be much stronger than 6061.
