I am starting to get the parts together for a new motor. I am looking at what components to get and am stuck on the rods. What is the difference between 5.7 and 6.0 rods??? I have a stock 79' block and dbl. hump heads that are stock (not cut). Could someone give me the low down on the difference here..... I am trying to do as much of the shopping as I can in order to learn a thing or two about the whole engine building thing. Thanks...

The 6" rod simply gives you a more favorable rod/stroke ratio . This will slow the dwell time of the piston at TDC , creating a better cylinder fill , and ultimately more power . I would highly suggest using the 6" rod , even longer if it is in your budget to do so ,and if you are running a limited intake class .

The 6" rod is a common rod length to use in a 350 engine , so shelf stock piston's are plentiful . The difference in the price of a 5.7" and a 6" rod is nothing , and the piston's will cost the same for either combo . You will gain all the way around .
