I want to put a 400M in a 1970 mustang
Which pieces do I need ?

Thanks

 

OK, I'll bite, why a 400 in a mustang?

Hello
I live in Argentina and the others V8 that I have found are to expensive ( 2500 US) or have bad cores (bad crank or rod).
In argentina is very difficult to find American V8
I found this 78 400 fully loaded ( air ,steering pup etc) that have 50.000 miles on it for 1300 US dolars.
The setup will go like this:

Carburetor: Road Demon 625CFM vacuum secondary (300US)
Intake : Offenhauser dual port (252US)
Cam : Rhoads cam kit 220 @.050 and Rhoads variable duration Lifters (169Us)
Pistons: dynagear 9.0:1 (128US)or 351c modified 10:1 (around 300US)
Heads: stock ported (by me)
Headers:thorley 4 into 1 for a 400M in a 70 mustang (around 200US-300US)

The problem are the motor mounts and the bolt patern of the trans.
I have a small block toploader , I think that it could fit whit some minor mortifications (help in this section please).

The motor mouns have 3 pieces in almost all ford v8 engines:

motor pad (unique in 351M/400)
motor mount
and the chasisn mount
I have the chasis mount on my car , the engine have the pad , so I must MAKE the motor mount I think.
Can I put 351C motor pads on the 400?
That will do the thing much simple.
The pad that rest on the engine is the only one that absorb vibration? , if so can I make the motor mounts from steel only
(no rubber)?
Finally :
I want 380/400 hp and 400lb of torque.
It could be done whit a 305 but it would cost a lot more.
It could be done whit a 351C/W yes but I do not find this engines very often and cost a lot more.

THANKS

If someone need info abut the engine setup email me.

 

This guy needs to use 429/460 mounts and bellhousing
doesn't he? Did Ford have a 429 in a 70 mustang?

 

Im just guessing, but I think the 351c mounts work, and a bell from a 429/460. Not sure if a 400m bell from a truck 4spd would work on that toploader.

I'm not too sure about the transmission, but the 351c has engine mounting pads the same as the 289-302-351w, just 2 bolts in each side. The 351m-400m have a 3 bolt mount, similar to the 429-460. I don't know if the 460 mount will work, however. maybe someone else knows for sure.

 

A 'C' has small block mounting for the motor mounts (same as a 351W) while the 400 has smoething totally different.

It probably isn't exactly the same as a 429/460, as one of those won't bolt directly into a bay where a 400 once sat (hence the need for L&L.
