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.

What block are you using?
