Tail of a 400m . . . . - Pirate4x4.Com : 4x4 and Off-Road Forum

mustange70 · 07-06-2009, 11:35 AM

If you seen my predator carb post you'll know that i toasted the valve train in my motor, and as such we decided to go full roller, and a tad bigger on the cam, anyway a few details:

fully balanced bottom end, arp studs on everything, inculding the heads, 11.5:1 compression, roller roller cam, roughly .685int/.700exh lift cam (its just a "little" guy of a cam

) ported and polished 4v quench heads, ported roush b351 intake with a predator carb to top it off.

It will be getting ran on a dyno for break in and some numbers, so be looking out for a video and dyno sheets.

Lets get some prediction on some hp & tq numbers here,

i'm predicting a conserative 550hp with 500ft lbs of tq, with power to 7k rpm. But that was with a smaller cam, soo i think its going to be a tab bit higher, will probably flirt with the 600hp mark pretty easy

so heres a big

to all them peeps who think the 400 is just a boat anchor, but than again most people probably ain't gonna believe that its a 400

Rekless_Off_Road · 07-06-2009, 01:44 PM

A 400 big block? Or small block?

Either way, I would like to see that boat anchor make that much horsepower at that high of an RPM.

ButtNuttN8 · 07-06-2009, 02:05 PM

the 400 is a stout motor just people dont beleve it.. and somtimes it costs more money than its worth. did you do the 351c head swap? thats the easyest way to unlock the anmeic engine. you musta done something if your old motor was 500plus hp anyways good luck I build up a 400m pay a shitton of cash for it but the jack ass put the waterpump gasket in backwards and it was pumping coolent into the engine.

mustange70 · 07-06-2009, 03:55 PM

old motor was probably right around 450, it had a smaller cam than i though it did (the replacement for the 275DEH was a 270H which was a dog in the motor). And yes its the 4v quench heads on the motor.

And BTW 400's are small blocks

Not exactly a 400m isnt really a big block or small block... Ill let someone else explain but its a 3## series I cant remember the exact number.
Either way its still a ford and props for not cheaping out and building a chevy.

mustange70 · 07-06-2009, 04:25 PM

335 series, but this board likes their small block chev shit, (which has no place in the mud), so i thought i'd dumb it down a bit for the chevy impaired

. I'm also kinda stuck with ford anyways, since my last name is Ford

Hillbilly Rockstar · 07-06-2009, 04:33 PM

Good luck with the motor, hope it turns out the way you wanted it.

Who's doing the dyno session for ya?

cslimfu · 07-06-2009, 04:41 PM

i never did understand the split between 335 and 385 series. i figured with canted valves it would be a "big" block. plus it has a longer stroke than a 460. a buddy has one that stomps my 460

he went mega cheap on his build with pistons from napa for a propane motor(11 to 1 i think) and hogged out his heads himself. i had one too for a while. they run strong and always catch shit for some reason.

Rekless_Off_Road · 07-06-2009, 04:43 PM

Don't know crap about Ford's never wanted to. Chevy does make a 400 small block and a 400 big block.

Didn't bother to search on the 400M and for that I retract my previous statement.

Should have built a Chevy, maybe you wouldn't be having to rebuild right now.

cslimfu · 07-06-2009, 04:45 PM

by 400 big block chevy are you speaking of a late model 396?

Jrod-13 · 07-06-2009, 05:17 PM

570/530 is my guess..
400's are a bad... bad.... motor, especially when you put some compression into them.. 400ford>400chevy... but then again, it's not even really a fair comparison..

But shit... my cousin's buddies uncle 350 puts down twice that with stock camelbacks, a 3/4 race cam, headers, and a Qjet on a high-rise.. course' that sweet autozone chrome kit really sets it apart...

cslimfu · 07-06-2009, 06:30 PM

what is the other 1/4 of the cam? part "race" or not "race" at all? is full "race" just too crazy or what? ...................oh, damn. now i see what you were doing.

mustange70 · 07-06-2009, 07:20 PM

hillbillly, its being dyno'd in great falls MT, the builder is doing the break in, pulls, if it times out right I'm going to try to be there but that will be on saturday, or my father will be down there if it gets wrapped up and put on the dyno on friday. I'm hoping it gets done on friday cause i'll be racing for saturday then.

true enough, however the heads from any small block can be bolted to the 400, most 351C parts swap over that aren't dependant on the deck hieght, the crank from the the 400 can be made to fit in the 351windsors and clevelands.

Basically other than similar cyclinder head design theory, and the same bellhousing pattern, then again the 400 can be found with a small block pattern (had the old FMX tranny behind it certain flywheels and starters will interchange as well) the distributors are the same piece as well. Its more or less a big small block or small big block, but not a true small block or true big block.

It's a Medium block, duh, what did you think the 'M' was for?

I know thats not what the M is for,
I know there's got to be at least 2 stupid fawks that ARE going to argue about it

Not sure why you went there but nice motor. I'm actually building a 400 sbc right now. Of course i'm actually building it myself

KyleQ · 07-07-2009, 02:30 PM

My father is hellbent on building a propane 400M - and build specs or advise on what he should be doing while it is apart?

I'm VERY eager to see what kind of numbers you are going to put down - I'm going the route of an EFI 393 with a high probability of a 100 shot for the tough spots.

Hillbilly Rockstar · 07-07-2009, 05:29 PM

Have you ever thought of getting those Jon Kaase aluminum heads for the M? I bet that would net ya some decent gains!!

mustange70 · 07-07-2009, 05:45 PM

I fi were to go aluminum i'd be raiding a nascar ford engine builders parts bin

LMAO I met a guy that swore up and down he had the 400 medium block in his truck.

mustange70 · 07-09-2009, 07:23 PM
