Hello - new to the forum with a torino project

1975 on up, H code could be either the 351M or the 351W

What that means is your car started out life with a 400.

One way to tell the difference between the 351C and the 351M/400 is the size of the transmission bell housing. The 351C has a smaller bell housing, while many of the 351M/400 transmissions have the larger bell housing. The picture below is of a 351C transmission, notice that the bolt holes on top of the bell housing are close together and the bell housing is shorter.

Welcome, and looks like a fantastic project.

So .. If my past experience with Ford is any indicator, the 351 C and the 351 W engine should be able to use the same bell housing .. is that correct ??

I had a F350 dump truck with an original 351 W engine, manual transmission. I took a 400 engine out of an automatic transmission F250, and put it in the dump truck. I needed to get the correct bell housing to go from the ( T-800 ? I think ) transmission to the 400 block with all new clutch kit and find an actual flywheel, not just the flexplate.   This is what makes me think that the 351C and the 351W have the same bell housing pattern, since you say it's smaller than that for the 400.

hummmm ... well I just checked .... and the top bolts of the bell housing in the S&H are about 7" 3/4 apart. If memory serves that's the same size as that 400's bell housing that I had, because I think that the 351W bell housing top bolts are about 5 1/2" apart. So ... I read some bad info on the net ?     I read that the 351C had vertical fuel pump bolts and that the 351M and 400 had horizontal fuel pump bolts.

I guess at this point ... I'm no longer sure what engine I have! ... but I guess that if it's a 400 .. it's more likely to be the original engine, because they stopped making 351C in 1974 ..is that all correct ??

Some 351m and 400s were drilled and tapped with the small block pattern too

No I don't think I have the morphadite. I can clearly see the bolts on the top of the bell housing, they aren't tucked under like that block in the picture.

I've seen exactly one of these, and it had both bell patterns drilled. It also had the bosses for the 302/351W style motor mounts, but they weren't drilled.

Hi All, been a while.

I seem to be having some trouble with my radiator. I'm wondering if anyone has any suggestions on where to buy a nice polished aluminium 3 or 4 core drop-in radiator for my S&H ?   The one I got from Champion Radiator was pretty nice, but there were some grinding scratches on the top from an uncontrolled grinding wheel. That was very disappointing. The other thing, and I suppose I shouldn't be surprised, is that they won't give any credit for the return of the damaged one, toward a new one. So I'm looking elsewhere just to have a second look at all the options.

Indeed. Of course I only realized that after I got over the initial shock of an incredible amount of steam and water spraying all over my chest as I was leaning over the spinning knives adjusting the throttle.   


Incidentally I did take a measurement of the stroke in cyl #1 and it is 3.5 inches. I've also determined that it is 99% certainly an original 400 block that was cranked / cammed to a 351( C ?   is there a difference ? or just in the heads ? ).

holy schnikies! how tight was the P/S belt?

Please correct if I'm mistaken.   I thought that the 351C absolutely had the _smaller_ of the two Ford bell housings ? The top bolts on this bellhousing are 7.5" apart, which is the same as a 400 motor I have in a F350 dump truck. I believe that is the larger bell housing pattern ?   The Windsor engine and bell housing that was originally in that 1983 F350 were the smaller bell housing with a top bolt distance of about 5.5".

I read somewhere that the 351C never was made with the larger bolt pattern .. so that's why I thought it was a 400 that was restroked and recammed to 351C specs. But I guess that's another thing I'm not clear on. The difference between the 351 and the 351C _exactly_.

After I finish the brakes on this other vehicle I'm going to see if I can get under the car and get the block # somehow.

" the standing rib next to the distributor is the tell "


standing rib ?   sorry .. I'm not 100% sure what you mean ?

Ok Rockymountain, then that means that I've got a 400 block that was either originally a 351M or 400 stroke, but that is definitely now a 351 stroke. There is a CAM sheet that I found in the car. I'm not sure what it means exactly.

that's the Summit 1792 cam LOL
