Dave,
I have always been a big fan of RPM small blocks, go for it. A friend of mine just built a 4" bore with a 2" stroke. You should hear that thing

If you are going to use it on the street i would beware of the ally rods, I had a set from Miller that were called street duty for my old 6/71 blown 427 Ford and they stretched
Its aweful lonesome in the saddle since my horse died.

Aluminum rods are as strong if not stronger while under engine load.

When you wind it up, let off the gas and let the engine slow the car down is where you risk stretching a rod on the street.
