318 build problems & new direction

LOL.. .no spanking! No, I'm just going on my faith in a lot of Mopar guys who have gone before me. (Plus some common sense engineering on the lighter weights.) In reality, I'm just taking the general 'word' for it that the SBM cast cranks are good to over 400 HP.

I never saw any info saying that there was a difference in the different cast cranks' capabilities, but it may never have a come up. I kinda assumed the 273/318's are all the same early or late, but then again, the later 318 cranks went with heavier rods so I can be all wet on that.

If you have an early 273 cast crank and late 318 cast crank side by side and had some pix, THAT I would be interested in seeing. I just don't have that big stash of SBM parts around like a lot of guys.
