400 casting numbers

In my library I have 3 numbers for casting numbers for 400 blocks : 3614230 , 3698630 is a 400 passenger , and , 4006350-400-12 . I may have the 360 inverted , could be 530 . A cool thing would be a 383 crank and rods in a 400 block . .030" over yields a high revving 403 cu in. smooth running combo .
