I found a Cleveland!

Bill, instead of a Cleveland it may be what they call a modified. I still think it is somewhat Cleveland like and I am not sure what all they changed when they started calling it a modified, but I think George can tell ya for sure. Don't be too scared off by that because Gary's monster motor is a modified too, only it started life as a 400 modified I think. But there is some little differances, just not sure what they are.

Probably a 351M.Same headbolt pattern but I think the bellhousing is for a BIGBLOCK.Low compression with 2v ports and valves.Correct me if I'm wrong George.

The 351M & 400 are members of the 335 series engine family, just like the 351C.

The blocks are 1.1" taller than the 351C block and, with one exception, have 385 series (460) bellhousing bolt patterns and motor mounts. They were equipped with 2V heads, and lower compression ratios, and lower power figures. But these motors can be made to perform relatively easily. The Bronco owners & Ford truck enthusiasts all love the 351M & 400 motors.

To be technically accurate, there is no consensus what the M in 351M stands for. The W in 351W stands for Windsor Cananda, the C in 351C stands for Cleveland Ohio. I have always assumed the M stands for Michigan. Some of the M blocks were cast at the Michigan castng center, but some were cast in Cleveland, so......its just an M. it doesn't stand for modified, although that is one of the common myths. Another myth is that the M stands for Midland. True, there is a city in Michigan named Midland, but it is not where the Michigan Casting Center is located. The 400 is just a 400, no letter in the designation at all.

There was one 400 block, cast in 1973, used only in 1973 autos, referred to as the FMX block, because it was designed to allow utilization of FMX transmission with a small block bolt pattern attached to the 400/351M motor. The casting number of the block is D3AE-B, and also rumored to be D1AE-A2C. This would be an ideal block for replacing a 302, 351W or 351C with more cubic inches. See pic below, courtesy of Dan Jones.

The 351M/400 truck block is a heavier duty block and is the best block for performance builds, the casting nmumber is D7TE-XXX (several suffixes). The late model passenger car block was also beefed up, because the earlier blocks had cracking problems. The number for this block is D8AE-X (several suffixes), this would be the second best block for performance builds.

351C 4V heads bolt right on, and intake manifold spacers are available from at least 3 sources to allow fitting 351C 4V intakes too.

Comp2's (Gary) new 434 Pantera motor is based on a 400 block, using a 4.25" stroke Windsor crank, and CHI 3V heads.

351M & 400 motors were common in late '70s through '82 Ford trucks. They took the place of the 360 & 390 FE motors, then in 1983 the 351W became the more common truck engine.

Disclaimer: I'm not at home where my reference books are, and I don't have to contend with 351M or 400 issues very often, so if I'm off with any of my data, please go easy on me.

The main issues you will have with a 400 or 351M vs a 351C is Big block bellhousing, engine mounts, clearance from taller deck/head height (small issue at the corner of the inside wheel well), and limited intake manifolds which make getting it under the engine screen harder. You are dealing with a block with the same bore size and spacing as the cleveland. Many parts will interchange.

People called it a "Truck motor". It was a truck motor as built:

It was the block I was interested in. The block (except for bellhousing) was basically a stroked Cleveland to start with. Stroke it a little more and you have easy cubic inches. Hard to beat easy cubic inches. With aluminum heads should be around or less then the original weight.

I have heard more "pastard truck engine" coments from when I started this. Does this look like a "pastard Truck engine"?

By the way, core charge was $50.

The intake is the same width as my car and there is a little 2 in the corner of the heads. I do belive i have found a 2bbl motor!

A 351M will be wider then a 351C for sure. The 351M is the same block as the 400.

Bill,

If this motor turns out not to be a Cleveland, I have a 4bbl Cleveland sitting in my garage that I no longer need. Call me if you'd like. 347-558-8745. I hope all is well with you.

Bill check out this site:www.fordmuscle.com/archives/2001/11/351m/.It tells everything you want to know about the 351M/400

I made the ID, It is a 2v cleveland, built to drag race. I offered him $500 for the whole truck. He is thinking about, he said he may let me paint his little Ranger for it. I'll know more when I hear it run. If it has a nice thump to it, I'll clean her up paint her blue and stick it in. Then do a seat of pants dyno. I'll keep yall' posted.

I saw a 72 Grand Torino wagon on my local rollback. I tooled along behind him to his salvage yard on my 500 cc bike. Opened the hood from outside the car, the front end is very nice. I bought the 70k motor on the spot . It is 2V and very clean... I'll post pics soon. Maybe I could run this with my borrowed trans until stroked 383 GP?

Whatever happened to the pick up truck?? Did that one fall through??

Bill you'll need some 2V headers, a flywheel for a 2V motor, and you'd probably want to pick up an Edelbrock 4 barrel carb intake for 2V heads (Performer 2V) on ebay, plus a Holley or Edelbrock 600, because I doubt you want a 2 barrel carb on your Pantera. The 2V motors run pretty good with a 4 barrel carb. Don't run a carb bigger than 600 cfm, because you'll just float the valve springs if you rev the motor too high. Drop in an MSD ready to run distributor so you won't have to adjust points, and go for it!

I found a Cleveland too, it's in Ohio north of Rt80 right on a lake. Small world.

The old man keep saying he is going to let me hear it run...but then nothing happens. I just happen to see the Torino go by!

$250 My motor is better, cleaner, Does this look like stroker beginings? How much horspower could this block support? Gulp, Gulp
