Shortening a Scat Crank

Can a forged Scat 4.5" crank snout be shortened to the Boss length, fairly easily for a good machine shop ?

Determined I'm going with a 12/71 kit from Hampton

Yes and get it double keyed

What are the advantages to the boss length crank snout othere then more room between radiator and balancer in a N/A or nitrous engine?

Because the damper and pulley are closer to the front main bearing, it has less leverage so it is stronger in use.

I've heard you can have it set up for a small block damper or is it better to stick with a big block damper?

YES ... a 3" long snout for using a small block damper has been done for years but, is now becoming popular.

Another option to snout shortening is that you can also play with blower hub and pulley orientation and get the lower pulley right up against the timing cover that way while keeping the standard length snout. This also leaves the future possibility of a bearing support if you care to add one, keeps the crankshaft more resellable to the masses, etc.

Is this a Boss snout then?

3.600" is a Boss length snout.
