woa, if you are doin g a complete build up, please at least turn it into a 400, you only need a 400 crank and pistons, also high compression pistons can be got from tim meyer, talk to him TMeyer, Inc. Precision Automotive Machining

Nope, wrong, the 351m and the 400 use the SAME rods, the difference is the crankshaft and pistons, the crank gives the stroke not the pistons, be carefull with this..

There is a lot of good information on the net about building a nice 400. Seek and you shall find. A good set of closed chamber heads will help get you to the compression you want fast. Look up MPG heads.

M-Block 351M/400 History
Th whole story, read where 351ms are introduced,
351M/400 Performance Build Up
Read adding more cubic inches section,
Your manual is WRONG, so again be carefull in what you order, since it may not contain a crank shaft or thepistons needed

The crankshafts are different in rod throw heights,and that changes the stroke length.The 351m pistons also use a different compression height.The only common thread in the two crankshafts is the journal diameters.The connecting rods are the same center to center length.If you are going to build a 400,you will need a 400 crank and pistons.
