  All small block rods are the same length, 273, 318, 340 & 360. Some have floating wrist pins, late 318 & 360 are not floating.   :bigsmile:

 The guy that built the engine I'm buying really likes these rods. I was concerned that they were not a very good rod when he first told me that he used a 273 rod.
  I know there are plenty of after market rods that are better, but it sounds like these should be great for my little street car. He used the Ross 99786 Piston and a MOPAR 4'' Crank (it's a 340 stroked to 416). We settled on the Comp Cam XS274S (20-230-4), an Air Gap ED Intake, J Heads, Hooker Ceramic coated Headers and an 800 CFM Carb.
  This should be a little stronger than my 318..............
