CanAm 430 engine
 

This was an all aluminum/silicone 430" big block Chevy with a 10.2" deck height sleeveless block. Bore was 4.44 and the stroke was 3.48 with 7" connecting rods yielding an over 2 to 1 rod ratio. The aluminum pistons were zinc plated, the plating held up pretty good because of the high rod ratio.
