What was the stroke of a Chevy small block in 1970?

STOCK RODS. As stroke increased from 3.00 to 3.25 to 3.48-inches, rod length remained the same. With the arrival of the 400 small block in 1970, there wasn’t room to maintain the piston compression height that GM desired with a 5.7-inch rod, so the engineers shortened the rod by 0.135-inch to 5.565 inches.
