Outer Limits 4x4 Board

Hi guys i have searched the forum but found nothing on putting a ford 351 into MQ.

What i need to know is what has to be changed? i know i can use standard water plumbing but what i really need to know is what will be needed to make my 5sp bolt up to the 351?

can i use the clutch that is in it or do i have to change?

Will i need a different input shaft?

will i need diff bell housing?

will i need an adapter plate?

can i buy pre made engine mounts?

thx

i have done this conversion in swb 351 ford very easy if you have petrol
gearbox as it is longer in the input shaft use ford 11 inch clutch and get the
conversion kit from dellowautomotive in sydney come with engine mounts
hope this helps.

well vcharter i have the diesel 5 sp? but could i use a petrol input shaft?

also the conversion kit what does is it consist of? i had a look at dellows and couldn't find anything on it?

thx for any more input m8.

I have done a 351 conversion in a shorty 40 cruiser.

Used standard Ford 11 inch Clutch
Marks Adaptor.
You will also have to swop to a Bronce Sump and pickup $$$$
so it clears the front diff.

Kit consists of
bellhousing adapter
engine mounts
new clutch
brass bush

if u get a full kit for the 5 speed diesel model, then ur problems will be very minimal with regards to the bolt up.
ford pressure plate,

can even use the diesel clutch plate so it lines up on the gearbox spines and use the ford pressure plate to bolt to flywheel.

all piping to engine bay will need some mucking around but will fit and stock radiatior will cool it depending on the fan setup u choose to run...

ull need to add a new rubber section of fuel line and a filter etc for the petrol motor.......

u will also find that ur motor will be far back against the fire wall and may require a very very light " massage " to fit the V section but nothing major.........
once agains depends on the kit and mounts u get and use.

cheers

Wrong

Because it will slip

The choice of clutch plate will be limited by the choice of pressure plate, for example if its an 11" pressure plate then there are other options from the Nissan range that will fit and work well but these are very limited options ( a choice of 1 plate only & farkin expensive one too )

If however its a 10" pressure plate then I'd recemend the clutchplate from a 99 model TDI ( 260mm dia ), there are around 4 differant plates to choose from in the 10" size.

The std MQ / MK diesels ( either turbo or non turbo ) are not large enough diameter wise to cope with the added power...... The "Z" series from the likes of the 260Z range are similar in diameter and will also fail eventually.

They will work ok for a while but a droplet of water or even the slightest amount of incorrect adjustment will see the motor being removed for a new clutch plate.

I have a dozen odd SD33, SD33T, 260Z, etc etc clutch plates here that have failed when fitted up behind a V8...... two of the plates came out from behind a 253...... your welcome to take a few if you want to try em !

been here done that

from memory i believe that your patrol is the only one to have any problems with clutch slipping with a diesel plate and holden / chev pressure plate.....
so u went and bought the bigger clutch plate.... when all along the main problem was your clutch slave and master cylenders
at least thats wat ive heard

i have the diesel plate, and have done 8000kms with the v8 in front of it with new clutch master and slave and i have never had any problems with slipping and been through mud and sand.

maybe with an 11 inch ford plate u will not be able to run it but behind the holden or chev, no dramas.
mine works fine cause my cylenders werent shagged

You "heard" wrong....... yet again


As I said ..... there are a dozen odd plates in the loft from OTHER rigs that have failed simply because the diameter isnt large enough to cope with the power of a V8.
I replaced the master & slave cylinders after the large clutch kit was installed and this was done in order to remove the "slop" in the system both in the linkage and the hydrolic sides of the equasion & both at the master end and at the slave end of things. I also machined up new larger diameter rods and redrilled the actual clutch pedal arm and fitted a larger diameter hinge pin simply to remove any slop from the system. All this was done in order to reach a higher "strength" level for the heavier duty pressure plate which I run ( mine is not a std holden pressure plate unlike the one fitted to your rig )
Use ya brains sunshine, shitty ole cylinders dont allow SLIP .... but they do limit the amount of THROW .... most ppl when doing this type of conversion make simple adjustments to the system so they gain the minimum amount of throw required to get the clutch to a point where the gearbox can be used without grinding any gears & to get the clutch to release, this leaves a very fine line between slip n grip with virtually no room for error ..... its this fine line that usually ends in tears and a removal of the engine so a new clutch can be fitted.

8000K's hey jesus I did that last month alone !
I also dragged around a triaxle for 2600K's last week with an average of 2 tons onboard....... comment when you have the kilometers up like I have instead of being shed bound and dreaming.
With the huge distance of testing you have done, all 8000K's of it since it was fitted over a year ago, I'd fully expect it would still be working ok, specially seeing its "parked" for such a large percentage of its life !

Mud & sand has little effect on a clutch plate in the short term, water on the other hand certainly tests them out especially after a deep river xing where the hot clutch pak has been fully emersed in cold water and the rig is then required to climb up a steep bank...... youve done how many of these types of crossings in your 8000K's of driveing ? ( street gutters do not qualify here ! )

The original poster is asking about the requirements for a 351 CI engine which has a very similar power / torque to the 350 chev which I run. While the HP readings from your 308 are similar in relation to the 350 & 351, its the engine TORQUE which is vastly differant. Its this extra torque that you have not yet experianced that WILL see a std nissan diesel clutch plate SLIP & therfore fail eventually.


In my experiance the std SD33 & SD33T plates do not stand up to the type of terrain I drive nor do they handle the excessive loads I regulary drag around. I have found that even a 253 V8 will distroy the SD33 & SD33T clutch plate under similar circumstances and yes I have the farked plates here to prove just that !

but what would I know ....... I'm too busy DRIVING mine

Where is the love?

Domestics don't yah love em

What is this one plate only that will stand up to the 351 that is so expensive.

well done dude. doing 8000kms last month in a SOA V8 MQ, thats good work. i wish i could do all that highway driving in my comp rig

Any body know of the different mounting systems of the EFI 351 in the F Trucks compared to them in lets say the sedans.

im not 100 percent certain on the types...
but i have a little info.

i used to work at repco and i know from memory that wen i was selling the engine mounts from say an XF etc compared to that of a F150 etc the rubber mounts and chassis mounts them selves are different.

i am unsure y, but the engine mounts are different, though there are still only 2 and they arent that different......

possibly harder rubber and mounting system for the heavier drivetrain of the F series.... unsure..
