Re: How does Crank/Rod/Piston Weight affect mpg?
Hi Patrick - Recently I had a 351E rebuilt - I had planned on using the 426 Hemi rods and the NOS 379 .040 over pistons I had - ( couldn't use the standard rods because the 379 piston pin height was closer to the top of the pistons) so figured this would be a good time to offset grind the crank for a little more stroke. Ended up the machine shop won't use the Hemi rods because of the amount you would need to grind off the crank journal and the difference in wrist pin diameter. So we went with longer custom billet rods to make up the difference in rod lentgh and left the crank alone - not a cheap overhaul but at least there's lighter and better rods. I would probably not do this again. BigblockV6 and I discussed this rebuild many times - he's a good source of knowledge. Cliff
