I have built some small chevys and one big block. I have a question for the engine builders out there. I know there are quite a few here with way more smarts than me. I have done a 406ci small block with the 6" rods in it. I have seen some 454's with the long rods in them. I guess my question is what are all of the benefits of longer conn rods? And is there a reason not to use a longer conn rod for certain builds?? I was told it makes the engine turn over easier, not laying the rod over as much and helping the piston to travel downward without pushing it into the cylinder wall. Does a longer conn rod change piston speed as well?? If this has been hashed over already, I have been here for a few months.
Thanks for any thoughts!! Mike
