[DeTomaso] Fw: 351C Crankshaft Question

[Will Demelo]

Stay away from a stock crank on a high hp build.
A quality  cast crank will be fine up to 575fwhp (Scat says 650), so I 
stayed well below.
A forged internally balanced set-up is the way to go but will cost 
considerably more.
On another note....what block/heads are you going with?
