Vin #'s mean squat when determining the engine size on certain
engines like the 351M/400 or the 30/390.
You have to physically measure them.
The only way to verify what engine it is.... is to measure the stroke.
You do that by using a piece of dowel or rubber hose or something like that in thru the sparkplug hole.
You get the piston to BDC and make a mark at a point where you can get the second mark to it., Now bring the piston to TDC and make a mark.
If the distance is 4" the engine is a 400
.
If it is less than 4" te engine is a 351M.

Wait'll you see my 351M. 60' and 18MPG.
Your Vin Code will give the best clue,
F150 4x4 starts F14S
F150 4x2 starts F15S
Thats a 400, 351M/W had the same code, H, but its not a Wheezer, because ford didn't put 351W's in trucks.
