400 big block

I have a 72 400 and I have a 73 Steel crank 440 I plan on building a 452, I have had these motors stashed for a long time, I read in Mopar Muscle magazine about 10 years ago that the early 400 blocks the 72 and 73 are what you want, they have a thicker main webbing and make a stronger block! I saw a 400 Stroked 452 incher in a Duster years ago and man,
the 400 is NO SLOUCH!!! when built correctly!!! It is the esscence of MOPAR POWER!
