crank question
Hello, new to this posting but have done a lot of researching hear.
I have a 351M and a 400. I'm currently building up the 400 to put in my 78 F-150. I'm unable to find the casting numbers on the 400 crank. All I see is 3 s's or 5's kind of stamped overlapping. I know it's a 400 because of the stroke comparison with the 351M on the the engine stand next to it. Could this be an aftermarket crank?
Second question. What are the nominal diameters of the mains and rods journals on the 400 crank.
Thanks. You guys have a great site hear.
