340 or 360

umm..is 8 cubes going to make THAT big a difference?
And, is .040 that big a deal? Hell, my 360 is already .030 over.

Is it possible to go to a bigger crank with a little block notching anyway and get past the 4.0" stroke?

I think it's a mute point...360s are every bit as good as 340s. They just don't have the fame because Dodge never built them as Muscle motors. If they did, I'm confident IT would be the famed smallblock and the 340 would have the status of 318.

I think it's just a matter if the owners wants to be able to say that he has a 340.
