Without trying to sound like a smartass, and speaking as a multiple Stude owner ( with Stude power and SBC power) I can tell you that the long term personal satisfaction of building a Stude motor will far outlast a small block.
So will the Stude engine.
The blocks have more nickel in them (read that harder)...
He heads don't need hardened seats (waste of money)
The crank is forged.
The cam is gear driven.

Sure, the parts may cost a tad more, but if you decide to stay Stude powered, give me a call and I can get you some deals on the parts.
