Hi, I'm new to this site and new to slant sixes. What I have is a 65 valiant signant 200 w/a 225, auto tranny. When I purchased the car, I didn't think the engine was original to the car. Due to the block being orange, oil pan is red, head is blue and the valve cover is orange. So I checked the casting numbers. 2463430. 1966 block. The stamped numbers are V 22 8 13 2. Can anyone decode my numbers?
