Waste of time unless your class rules require a small ci engine. I have built a couple small crank engines for class racing reasons, but the power in reasonable ci is worth using.

You'll basically end up wasting a lot of time and money. What you will have is an engine with considerably less power and torque, yet can't rev any higher because you'll be limited by the valvetrain. Stock 3.622" stroke streetcar engines are turning 7-7.5k RPM, while 4" stroke race engines are turning ~10K RPM.
