68-72 400 CID

X-mas morning I had to drive out to my mothers boyfriends house and I came across a Gran Torino station wagon. I asked about the engine and he told me it was a 400. He told me I could have the engine if I could get rid of the car. Any suggestions on what I should sell this engine for. I believe its also an automatic. Worth salvaging?? Same with the rear. Anyone interested in any of the above write me an email @ [email protected]. Thanks, Razed
 
No, they use the same style heads but the 400M's have 2v open style clevland heads that suck for performane.They also make a 351M that uses the same heads and block as the 400M but has a clevland stroke.
 
Build that 400 up like any engine. Good pistons, rods and a good cam with some clevland heads and it will run. PM dirtracer. He should have some insight on that motor.

The 400 has a long stroke (longer than 460), so it is not a good high RPM motor, but you can make power with it.

If you try to sell it, make sure you pull the tranny withit. Probably has a C6. Any truck owner could swap that into their pickup for a nice combo.

Also that car probably has a 9 inch rear. That is worth a few pennies to the right person. There is some $$$ potential in parting that car out.
 
Hot Rod did a build up a couple years back on a 400 and it ended up putting out close to 380 hp and 450 ft-lbs of torque for around $2000, using a 2 bbl carb and factory exhaust manifolds. http://www.geocities.com/styleline58/400.html The heads which are the same as 351c 2bbl heads outflow in stock form the GT-40,GT-40p, and Windsor jr so they are not that bad http://www.allfordmustangs.com/Detailed/630.shtml .400's came from the factory with low compression, poor valve timing and 2 bbl carbs so they weren't much in stock form but they can be made to put out some decent power.They are getting more popular as truck motors to replace 351m's but are a poor choice for a fox body.In 1973 some of the 400 motors had a small block bellhousing pattern and are more valuable so you might want to check into that if the wagon is a 73.

hllon4whls, the 400M isn't good for anything but some mediocer low end torque.For the sheer size of the motor a 429/460 or even a 390/428FE will make a better motor.

It is not quite polishing a turd, but they can be made to run without gobs of money. Look at the 302 before the 5.0HO. 150-160 hp 2bbl, etc, etc. A 351 windsor is a better choice for me personally, but the engine is free and the other thing is that it is not common. Bet people cant figure out what it is at a cruise night.
 
I said that they make a good trucl motor, but for something that is considered a big block there is better alternatives.Also I highly dout that they are good at making mid-high rpm hp.Because the deck height of the block makes it hard to have a short run intake, unless you got a tunnel ram.I don't know what to ask for it, maybe $250 for the motor and $100 for the trans, and $75-100 for the nine inch.
 
Weiand sells adapter plates to let you bolt a 351c intake onto a 400.Some people have stated that they really come alive with the 4 bbl 351c heads and the single plane 351c intakes.My Ford racing catalog lists the 400 as a small block engine and they share a lot of common parts with the 351c such as heads,distributors,oil pans,timing sets and cams.I can remember years ago when 351w motors were considered low performance truck motors and look at them now.
 
400

Just to clear any confusion, the 400 is referred to as a 400,
the 351 version of this engine is referred to as the 351m,
because it is a modified version of the 400.

Yes, it's wider, taller and heavier than a 351, and the
stock heads basically suck because of the open non-
quench comb chamber.

However, Cleveland heads will fit right on, including the
now available 2bbl closed chambered ones from AU, and
the new aluminum closed chamber heads I just read about.

I've read build ups for things like Pantera's where there is
sufficient room that got well over 400 hp and torque using
good Cleveland heads, Cleveland 4bbl intakes using either
the Weiand or the www.pricemotorsport.com adapters, and
a good Cleveland cam.

Having said that, they are more suited to trucks because of
the size of the engine, although they're still quite a bit
smaller/lighter than either FE's or 385 series. With all the
good heads now available for the Windsors, the 351 W's
are much better overall for most car applications simply
because of the size and weight issues.

Hit the nail on the head!

If you really want to find some info out on these motors and what they are capable of go here http://www.ford-trucks.com/forums/index.php? and here
http://home.earthlink.net/~bubbaf250/index.html Yes these are truck places and this motor is used mostly in trucks. It is a hell of a motor and for less than 1000 bux mine is quiet a beast so far. Bad thing on mine was Ford killed its power trying to reduce emmissions in 77 so it has a tiny cam, very low compression and a crappy motorcraft 2 bbl. all i did is freshend the heads and a little porting, rods and pistons which upped the compresion to 10:1 and a comp cams cam. it barks 2nd with my 35's and pulls hard to 5k
 
Damn fine engine there. Bombproof. It was used in heavy vehicles like big cars and trucks. Lincolns, T birds, etc. I had one in an F150, and it was strong enough to pull a 2.73 axle. Should have a strong c6 behind it. If it has a c4, then you can use the bell housing for a 460 in something. The car should have a 9 in, or maybe just an 8 in.

Worth having imho.
