Question about stainless steel radiator hose

[65 drop top]

I was making a template for a 304 stainless steel upper radiator hose but my friend said it might be a problem. He said that it might break or crack the radiator inlet tube when the engine torques. So my question is how much rubber hose at the connections is needed to make sure I don't run into any problems?

I'd say if you had 3/4" between the end of the rad inlet and the stainless tube and they're connected with rubber that you wouldn't have an issue. If you were able to use a 90 degree hose off of either end it'd help because it'd be on a different plane and would flex more because of the additional rubber.
