I am searching for Chrysler big block blue prints. 440 RB 1977. I cant find any blueprint info anywhere. i have a Rottler f65A brand new and i cant even begin to bore my block. im trying to find the centering point on the block. i have the bore spacing and lifter angle. i know you center off the dowl pin. but i don't know how far to go over and how far to go down. any help would really help me!
