Thread: Lincoln 400 vs. Ford 351

Tweet

the 351c, 351m, and the 400 were all in the "335" engine family. the 400 is the 351m with a 1/2" longer stroke. i think it's actually 402 or 403 cubes. it's good for trucks because that gets you more low-end torque but sacrifices horsepower on the top end.

my dad has one in his '78 3/4 ton. we put a new 280-300hp engine in it about 4 years ago, but even the stock motor had good torque. they sure love gas, though, and he has to run premium it it to keep it from knocking. i wouldn't recommend that motor if you had other options.

Well, Andy, you can call the 351 Cleveland a 335 block and it does share the same design, however it uses the windsor deck height, windsor motor mounts, windsor bellhousing. It was only produced from 1970 to 1973. Made a performance boost when I put one in my 78 Merc Monarch with 4 speed.

i'd reccomend staying away from a 400, they really dont have a lot of power, expensive to get a lot of power out of them and very expensive to keep your gas tank full, they get terrible mileage and need premium.....
