Been thinking about a 396" stroker myself. 360 block with a 3.79" crank. Is this how you're doing it? 318 base with a 4" crank?
BTW, Joe. You on instagram? I'm @5_points_racing . I don't have any Valiant content on there but it's coming very soon. Reiss Racing is doing the metal work now to fit 315's in front with a 335 rear.
