To Stroke, or not to Stroke

Is the tube K member set up for Rack & pinion steering?

Ok guys, I understand about the .30 over but .30 over what?
The 400 bore is bigger than the 440 right out of the factory, do I go to .30 over in the 400 #'s or go .30 over in the 440 #'s which would be just a little more than what I need to get rid of the taper in that 400 blk I figure.

I am thinking it would be to the 400 to get as much displacement as possible. Any advice guys, the engine builder is needing to hear from me.
