    Ford 400M engine build up

    I'm not a big fan of the conventional, even when it's in the context of something unconventional. So I fancied the idea of building a slightly different engine. I watched ebay for a while and eventually a Ford 400M came up. No gearbox and it was seized, but I got it for next to nothing. It sat in my garage for a while and finally I popped it on the engine stand (the long Rover V8 head bolts are the perfect size).


    I'm struck be the size of the thing - much, much bigger than the Rover V8 engines I'm used to looking at.

    There were the remains of the factory air cleaner, but the carb looks quite crusty.


    I pulled the manifold (which weighs almost as much as a complete Rover V8!) and the valve covers. Not too much gunk in the rocker area.


    The inlet ports are impressively big, but they're incredibly crusty too!



    So let's have some predictions of the extent of the carnage within!

    Cool, I'll watch this closely as I'm building a BBF at the mo and there are a lot of similarities

    Handy tip about the rover head bolts, are the bolts the same for 460 as I need some?

    The 400M takes a BBF gearbox, so I'd guess so. I'll measure them in a bit and post the sizes. Just gotta go back out and lie in the snow for a bit - my old Range Rover's big chance to show up the cars in the snow and starter decides its time has come!

    well it looks like we are on the same planet!..bought a 400m a few years back to fit into my fox body mercury capri.(similar to mustang)..its a very heavy old lump..but shares some bits with 351 lump...any way its finally in! but cant get it to run at the moment...it tries to fire but pops back through carb..timing is ok ...but gonna wait till weather warms up before investigating further...........but if you have any ideas let me know!!!

    Check timing again, dizzy timing and that your leads are on correctly. That'd be my first plan of action

    The bolts are 3 3/4" long and 7/16" in diameter. There are three lengths of head bolts, these are the longest. Maybe a bit too long, depending on your engine stand, you might be ok with the middle lenght ones. I used the long ones, but had to use spacers (old castle nuts) to get the lengths just right.

    basically the same as a 351 cleveland, main problem i believe is getting something other then an rv type manifold to stick a 4 barrel on, because of the higher deck height most performance stuff wont fit, not wide enough ! spose you could use a performer for a 351 2v engine and make up some spacers, that and aussie 2v heads and a cam and it would just be like a big capacity cleveland
    kev
    i say, anyone for a spot of tiffin...

    Edelbrock make a Performer dual plane manifold for them. This is mine:


    No-one loves the 400M it seems. Maybe that's why this only cost me £20 on ebay. (perched atop a Rover for the photo)

    With some trepidation I pulled the heads. No water in there now, but I think there was at some point!



    I'm guessing that might be why it had seized then. Game over for that engine then.

    As I said, it didn't come with a gearbox, so I'd been keeping my eye open for one and sure enough ebay delivered the goods:


    Fortunately the gearbox came with a 400M:


    So the 400M project lives!

    Still, lets not waste the spares potential of the first motor. I stripped everything out, hammering the piston out with a rod on the underside.



    Here's a shot of the thermostat:

    The small rusty lump sitting inside it was a dead bee. How the hell did that get there?

    If you want to store a stripped down 400M, you'll need a whole spare rack and that doesn't include the block:


    I'd lilked what I'd seen up to this point - big, big ports, huge valves (2.05" intake), funny shaped cylinders to de-shroud the valves. Lot's of 351C parts fit too so there's some choice out there. The 400 is basically a 351C with 1" more deck. The main journals are a different size and the extra deck height means the manifold, conrod and pistons are different. Most other things are interchangable though, including the heads.
