Addionally, up to at least 76, there was a motor option called the 360.
It was a truck only motor based on the 332/352/390 family.
I ordered one in a new 76 SC. Poor very poor motor.
In 76 I also got a 390 F250 HD and man what a motor that was with factory 4 barrel. It would run rings around any of todays stock offerings.

NOT!! The 351C is NOT a big block. Nor is the 400 acording to some... that is debatable. The engines availible in 1977 F-150's were the 300 ci 6 cylinder, the 351M and the 400. The oil pump drive shaft should be the same in the 351M and 400. Of course a truck this old, it is anybodies guess what engine is in there now.
Please visit this site in regards to the size of 351 Clevelands or Windsors.

You may be correct about cylinder spacing, etc. However, the Cleveland is noticeably larger than the Windsor and is based off of the big-block design.

Well after checking some catalogs, it appears as though we have a 400M. Going by the gear on the distributor and oil pump shaft length. Although both of those parts are identical on the 351M and 400M.

Should have it running tonight if everything goes as planned. Broke a bolt off on the pan last night, so we have to get that out. Shouldn't be a problem with the snap on bit retracting set I have at work. Should make quick work of that stubborn bolt.

again, the big block/small block is not based on the size of the engine, or that it may have some design features of the big block. The 351C and 429 even use the same distributor. But the fact is that the architecture of the engine is all small block. You can interchange a 351W and a 351C in a car with little wiring or coolant hose changes, and of course exhaust. But the mounts and transmision useage is the same between the two and that is what makes a 351C a small block. Trust me, this argument has been going on since 1970 when the cleveland came out. It is all small block. Or are you going to call a boss 302 a big block too? after all it has cleveland design heads.

351- C, M,a and 400

I've been dealing with these engines for years, and have built many cleavlands, maybe I can share some info I've gleaned over the years.
Firstly, the 351C is neither a small block or a big block, it's a mid- block, designed by Ford as a result of the Boss 302 racing engine. Ford figured it needed a larger block to extract all the potential out of the huge 4V heads, and the 351C was the result.
The 351M is a 400 block with a 351W crank, or a destroked 400. They share the same main bearing journal size, 3in.The 351M was built solely as a low compression, relatively low horsepower worker motor for pick ups, wagons, etc.
Hope this info helps!
