it cost no more to build a 4" stroke than a 4.25.
Killing a little bottom end of a stock suspension street car is not a bad thing. Easier on ALL drivetrain parts.
No one is telling the guy to put a solid roller or 11:1 comp.
I guarantee the OP would not be able to tell much difference in driving the 2 on the street.
