Thats actually "making the same kinda 400 no m"

dude the only difference between a 351m and a 400 are the crankshaft and pistons, so get a 400 crank and 400 pistons to stroke it, the rods are the same..... to get it to a 410 overbore it 40 over....

ok, you dont have to talk down to everyone. All you had to say was "you need the 400 crank and bore .040 over."

He has the same engine block that you do.It is a 335 series block.A 428 crankshaft belongs to a different engine family known as FE series.He will obtain the extra cubic inch through a larger bore size.
