I am in the process of installing a reman 79 460 into a 80' F-800. I think I screwed up because the casting numbers on the block of the engine I removed are D9TE-AB. I assusmed it was the 460. When I received my reman long block, everything is virtually the same except the crank. The crank snout on the old motor is about 1 3/4", the crank snout on the reman is about 1 3/8". (give or take on the measurement didn't have a micrometer to get exact) After doing some looking on the internet i have now realized that I possibly have the 429 commercial. Question is does anyone have info. on the snout size on the following motors from a 79' D9TE-AB, 429,370,and 460? I know that those motors all use that block. Thank you in advance.
