Unfortunately, as EdStainless noted 380 aluminum alloy is not heat treatable, and die cast aluminum in general has limited fatigue capability. About the only thing you can do to your connecting rod to improve its fatigue capability is shot peening. Here is a MIL-S-13165 which provides guidance on shot peening of aluminum.

Heat Treatment – A Brief Introduction
In general, heat treatment is a process of changing the material properties by ther-mal, thermochemical or thermomechan-ical means [1]. Heat treatment processes are aimed at optimizing the performance characteristics of an aluminium product. During casting, purely thermal treatment is usually performed, whereas wrought
