Stop with the finish you have and have the rods shot peened for addition strength. 6.8" Ford 240 six rod on an Autotec piston. https://dl.dropboxusercontent.com/u/39382077/Ford six/IMG_0009.jpg Paul
What are those going in a 240 six? The journal bore fore those rods are for a 2.123" rod journal while a sbb 350 has a 2.00" rod journal size. Is just an example of polished and shot peened beams? Nice job on the beams on those rods! how much power will you be making with them? Are those a forged or cast rod? But HELL YEAH, 6.800" rod for a sbb 350 would help get the piston MUCH lighter! Its a bitch trying to find a long rod with the small 2.00" crank journal, there is the Flat head Ford after market rods that are 7.00" with the 2.00" rod journal size, they even use sbb 350 rod bearings! But that about the only rod that's long enough to make a difference in rod ratio than others available. Would need a piston with a 1.238" compression distance to get to a zero deck with a 7.00" rod, MUCH lighter piston! Derek
It was just an example of shot peening The rods are forged and do not have the oiling hole in the big end which is a place of failure. They were only made from 1965-1968 Those rods are going in a Ford 300 six. The 300 rod is 6.2" versus 6.8 for the 240. The stock 300 piston and pin is 819 grams. I was able to reduce that down to 575 grams using the 240 rod with the Autotec piston with a 1.19" CD. Looking at 325 hp @ 5500 rpm. Head is CNC ported with sbc 2.02" intake and 1.60" exhaust Its a thing of beauty! Paul
You always get to have all the fun and people pay you to do it! Sweet job on that 300, what is it going into? And how hard was it trying to find those rods? I love they way you always have your name engraved into the AutoTecs! Nice way to put your signature on a build. As always some cool stuff Paul, keep up the good work! Derek
