Nope! The 351M/400 has a 429/460 bell housing pattern, different motor mounts than the 302, etc. In typical Ford fashion, everything that CAN be different... WILL be different. The 351M is also highly inefficient in stock form. They don't make much power, and get horrible fuel mileage. To install the 351M, you'll need a complete parts truck from the same era.
This being said, a 351W will bolt right in place of the 302. You may have some stuff on the front of the engine and exhaust to work on... but that's the best swap, if you aren't interested in stabbing another 302 in it. A 351C will also bolt in place of the 302, and shares the same motor mounts and bell housing bolt pattern.
This being said, if you swap another 302, make sure its a 1981 or older. The newer 302's are balanced differently, and use their own harmonic balancers and flywheels with a bigger external weight.
All 351W and 351C engines have the same balance as the older 302.
If the person you bought it from had any brains, it may be a 400... as the only difference between the 351M and the 400 is the crank and pistons. Therefore, at rebuild time... those are the ONLY two items it takes to convert a 351M to a 400.
TMeyer has a lot of parts for these engines. At one time, TRW forged flat top 351C pistons were cheap, and have the same compression height as the 400 pistons, but a smaller pin hole... but you could bush the rods down smaller and use them. TMeyer has all that stuff covered nowadays. They are a 351C/351M/400 specialist.
I am looking for input from fellow members who have/have had their trucks equipped (stock or not) with the 351 Cleveland engine. Are there any good experiences with it?, thanks (I ask since I could get a hold of one real cheap for an engine swap).
It’s me again with another boring question. I have tried researching but all I’ve found is mustang related stuff and that the buck tag was used during assembly so the workers would know which options to install. But I am curious if there is any info I can learn from this buck tag.
Hello all, I'm new to the forum and I have recently accepted a build off challenge. The challenge is a street legal vehicle build and will include a quarter mile drag race as well. Kind of a friendly build off but I have decided on a memorial truck of the first truck my grandpa and me built. The...
Last month when a main bearing started knocking over 3K rpm's, we pulled our 351M out of my son's 76 Ranchero and got it rebuilt and upgraded with a few choice items.
I know the stock 351M in our 76 Ranchero was a low-compression smog monster and did not make much power from the factory.
Hello, I need to repair my radio, 1967 ford trucks have a unique “one year only” radio. I’m not having any luck finding a schematic from any of the dealers who sell them. The only number stamped on the radio is BTL308164 Thanks
