I have been using them for several years with good results. Also using the same L2355F pistons. My machinist did touch up the big ends. http://store.440source.com/Connecting-Rods-RB-5140-Forged-Steel-NEW-Set-of-8/productinfo/200-1015/


By the time you buy good ARP bolts, MAG, shot peen, and resize stock rods you are talking similar cost $$. and still stuck with 3/8" bolts.
Seemed like a no brainer to me.
