I was reading in a old thread you had a 400m break a crank
is this common I know the ol 6.2 & 6.5 chebby's deisel was know for this .... my 79 did the same thing broke the crank toward the front of the motor..first crank I broke and I was only doing 55 down the hwy when it snapped just died ....

 

I have also had a 400m break a crank . Maybe the were just weak

 

Hi Guys ! What's a 400 {M} ?

Is that a Missouri thing ?

 

If anyone is wondering about Mil1ion's post, the Ford 400 is JUST the 400, while the 351 gets the M tacked onto it. But enough people call it the 400M that we know what you're talking about ;-)

I thought the (M) was for M-Block.

 

The m I think is for Modified, as this block style was based on the Cleveland, at least that's what I have been told over the years. I wasn't running the truck that had the broken crank, I got it more or less as a result. I haven't run enough opf them to know for sure, but years ago my dad had a 79 2504x4 that we got rid of because it kept shelling motors, so he got the diesel we have now. I do remember that it was a 400 in that 79. It wasn't treated nicely though...

 

The block is known as the 335 block, which was originally the 351C and 400. Story goes that Ford couldn't keep up production of the 351W so they needed another 351 block to put in trucks since the C was very much a car motor. Since the 335 block already fit in trucks (the 400), they destroked it and made a drop in 351. To differentiate it from the W they called it the M. Dunno if it's true, but that's the most common story of how it came around.

There isn't a Un-equivical answer for what the M stands for.

Discussion let us to believe it stands for whatever you want it to stand for.
Just keep it yourself as all it does is cause flaming.

Now, again, this forum needs to rally together quickly to a fully functioning forum.
