Ok guys im currently in the process of building a akra legal engine. Ive bought a stock piston, low tension rings, JRPW attack series head and carb, and a cl3 cam. The issues we are running into is that we are concerned about the rod. We are running 10.8 lb spings as well. So our last engine was stock appearing with flat top , gx160 head, billet rod, arc 6619 flywheel (which will be used on the new engine), and a cl 3 cam. We are concerned about the stock rod not staying together . The rules state we can run a "performance cast rod" and we are not sure what is so performance about a cast part.
So our question is what rod should we run? We will be racing every two weeks and dont really want to window a motor due to a 10 dollar part. Or is the rod even a concern running under 7000 rpm.
thanks for any help you guys have!
