You have to stroke and bore to get 408.
A 4" stroke is the biggest recommended. There are 4.1" stroke cranks out there but you start having issues with the piston pulling too far out of the bore. The decks just aren't tall enough to allow you to safely run more than 4" stroke.

Crankshaft 4.1" Hi, I use my 4.1" crankshaft with GEN-IV blocks often with perfect success. (1850 BW)
I fit a RaceTec Forged piston (.927" Pin and Rail Support) that is engineered for this application.
I fit my 6.125" Forged "H" beam rods, grind bore bottoms for bolt clearance.
True, there would be other reasons when this is a good/bad choice ?
