392 Ford....as a race engine?

Hey I know this isnt about 4x4s....but the enigine is what I have a question about.

Im rebuilding a 71' Mach 1 Mustang....and It has the stock 351 Cleveland engine in it. But I wanna switch it out for somethin a little more deadly [img]images/graemlins/AR15firing.gif[/img] ..... a friend was tellin me I could put a 392 Ford in there??...hmmm....he said he knows where a brand new one is...(crate engine)....for cheap. Now does anyone know if I can fit that in my stang.... [img]images/graemlins/bs.gif[/img]???

Re: 392 Ford....as a race engine?

that reminds me, has anybody read about the new FORD 5.0L Cammer crate motor? I about fell out of my chair when I saw where it makes it's peak HP... 6700 RPM! [img]images/graemlins/blush.gif[/img] That thing revs out like a 4banger! It makes 425hp there, but honestly I would expect quite a bit more HP from a custom crate motor that revs that high [img]images/graemlins/cool.gif[/img] I guess it wont be too long before truck engines are revving up like the crotch rockets [img]images/graemlins/shocked.gif[/img] [img]images/graemlins/grin.gif[/img] ... too bad the peak torque is where my 351 redline is [img]images/graemlins/mad.gif[/img]

Re: 392 Ford....as a race engine?

You'll definately need an entire new engine if you're going that route. You're 351C wouldn't work.
The 392 stroker motor that you're hearing about, starts with a 351Windsor for the base block, not a 351Cleveland.
IIRC, and it'd take a bit of research......
You can put a 400M crank in a 351C. Mucho modification to do it though. [img]images/graemlins/crazy.gif[/img]
As a bonus, that 392 stroker crate motor from Ford, weighs at least 100lbs less than the 351C.
You'll also need a different tranny, or an adapter, because the Cleveland and Windsor bell housings are different.

I about fell out of my chair when I saw where it makes it's peak HP... 6700 RPM!
Hmmmm, I don't feel that bad now.
My 425hp is at 4,500 rpms
Peak torque, 440lbs-ft is at 3,000.

Re: 392 Ford....as a race engine?

Anybody got any idea how those (ie: in general) Stroker engines perform? High rpm power? Problematic? Short-Lived?

Actually it runs out.....that the 430hp that comes out of the 392.....only comes if you've got....

1.the headers 2. and a 750 Holley Carburetor...

At least thats wha the spec sheet says:

www.thefordsource.com/store/motorsports/pdf/m6007a392_430HP_351_.pdf

Anyways It'd be nice for a Mach 1......but its like $7000 after you have it shipped.....cant say I wouldnt mind having it though!!! [img]images/graemlins/cool.gif[/img]

Well, if <font color="blue">Shovel</font color> would quit ripping up the roads, and trails with his, and give us an update, we might know a little more!
He's got a 347 (stroked 302) engine.
Stroker engines are inherently better on the low end of the rpm range.
Longer stroke does equal less high rpm potential, but produces much better low end grunt.
Perfect application for a Bronc'. [img]images/graemlins/grin.gif[/img]

Re: 392 Ford....as a race engine?

There was a time not too long ago I was researching stroker motors for my later Mustang..

IIRC, the information I was getting was that, for a "daily driver" I'd be happier with a 302/331 than the 302/347, similarly a 351/377 vs. a 351/392. The longer strokes were seeing more piston wear if I'm not mistaken, and shorter life.

Granted, different app.. not a low-rpm trail riding motor use.. I was looking more at high-winding autocross/road-racing. :-)

Re: 392 Ford....as a race engine?

Yeah I really can't comment too much on a 392 cleveland, but my 347 reminds me of a mix between the 300I and 302. It has great low end torque like the straight 6, but also has the great high end of the 302. Overall I'm really happy, I haven't been able to make it up the passes in 4th on the drive home until I dropped the 347 in. Off-road it is awesome, I recently did a little wheeling on some rocks. Light throttled over all the rocks with no problem. Now I just need some 4.56s or 4.88s and a detroit to be unstoppable.

I'm confused on gas mileage though. My speedometer is off due to 35s and 3.55s, so would that throw the odometer off also. Guess I just need to do some conversions.
