351M vs. 351W
I was told that the mains on a 351M crank and a 351W crank are the same. I done some research at work and found that as far as the part numbers go they're the same. So I got to thinking. Will a 351W crank fit into a 351M engine? Since I might be redoing the bottom end on my 351M I was just kinda curious seems how they make stroker kits for the 351W and not the 351M. If not....are there any mods needed to swap in a 400 crank? Will I need to use the 400 rods and pistons also or can I still use the 351 rods? If so... I might go that route.

351W & 351M mains are both 3". However, there is a timing cover difference which won't allow you to use a stroker 351W crank. Use a 400 ford crank of have it offset grind to whatever stroke you're attempting.

the 351m balancer will work perfect with a 400m
just learn to set timing by ear as the timing marks are supose to be different
after market have both marks
like the aftermarket flywheels have both sets of holes for 351m or 400m clutch even the ones made by ford way back when
why they didn't do this in the production run is beyond me

or 351c pistons
or 360 chys piston depending on motor needs
no winsor or sb cheby pistons don't work
compression height of piston is like
1.3ish for wheezer or cheby
1.65ish for 400m 351clev
1.717 400m ENGINE(351m is 1.94)aproxamatly
1.75 for 360chys
1.9ish 351m (uneque to the auto world)
