You're right, Mark. Looks like somebody bought ONE of them.

351C block




351M/400 block

I'm confused as well now....I just went and looked at my block and it is the way the 351C shows

See...we are human. I went and looked and found a few other 400 blocks that look like the 351C water outlet.

This thermostat we purchased from a local Carquest. We used it in a 351C engine.
Part #30089, just a few bucks.

This was delivered today. It is a NAPA THM 297 thermostat. It was $9.95 with free shipping. The NAPA website lists it as $6.99. At least he didn't try to make money on it.

OK...I have totally screwed up now!!!

The pictures that I have posted about the water outlet, I have them labeled backwards.

The large hole, is the 351C outlet, but without the brass restrictor.
Hence the larger hole.

SO...the 351C (top-hat) style of thermostat should not be needed in the 351M/400 block.

I am very sorry for any confusion I may have caused, when you look at Ford and Cleveland style blocks all day, I can confuse myself.

With the amount of work that you have done to remove the 400 from boat-anchor status, you're forgiven. Thank you.

Thank you!!

It does make me feel kind of dumb.

But as far as "boat anchors"

I am feeling that with the latest builds, we have a 434 that has now made over 620 HP on the street, if it fits, it can be the better choice.

Now the advantage that the 400 has, is in the last few years of being in a truck, I feel the casting are thicker and stronger.
If a 351C block was making 600 HP on the street, it probably would not last very long before it split the cylinders.

Boiled Thermostat for lunch. This NAPA 195* thermostat started opening at 185* and was fully open at 195*.

Might try this one until another one arrives.
