Clevland 351

[td lux]

Being an old engine would many people bother putting it in 4x4.?? For the money, weight, and fuel consumption would it be worth putting in a GQ?

Or would a 5L Efi be the better option?

[td lux]

The above is referring to a Clevland 351

[want33s]

I wouldn't hesitate to fit a 351C if the engine in my 60 shit itself (thinking about it now and the 3F still runs fine).

351 is a good strong engine and can be stroked to 377 easily for more torque/Hp.
Alloy heads, manifold and water pump will reduce a lot of weight as will extractors.
Upgrades such as EFI are a bolt on from several manufacturers.
Kits are readly available to bolt them into just about anything and adaptors can be bought to fit to almost any gearbox.

i have had both 351's/windsor and cleveland in f trucks and would go for the cleveland over the windsor as the windsor doesnt have the low down torque of the cleveland.in a car it would be a different story.

[Bad JuJu]

Good option, only dud thing is the dizzy is at the front of the block.

The Clevo can run some big numbers if needed.

[brad-chevlux]

for the amount of petrol or LPG you pour the top of it, it won't make a great deal of power.

I'd be going with a 351 windsor. the lack of torque in the F truck is due to piss poor intakes and headers and a very ordinary tune in the factory ECU

using an edelbrock manifold and the ECU and supporting parts from 200kw xr8 or from a 5.4L T series falcon will solve that.

by the time you EFI the clevo or LPG it, you might as well buy a late model EFI windsor

Hay Dude.

I had a XD 351 Clev in a Shorty 40 cruiser a few years ago.
It had 302 gas heads with the combustion chambers relived to give 10.5:1. compression
It was very powerfull with stacks of torque.
even though the dizzy was at the front it was the electronic XD type, and i could drive deep river crossings without a single splutter!
I used the ford coz i had it in a XD ESP i owned before i bought the FJ40.
I used it coz i had a good motor i new the history of.
Everyone thought it was a strange conversion at the time.
But after having a Chev powered 40 in the early 90s, i was rapped how good the ford motor was as a conversion.
It never leaked oil like the crappy 2 peice chev rear main seals did.
And it run the same every time i started it.
The only extra hassle is having to buy a Bronco of 4x4 F100 sump.

I have just bought a GQ 350 Chev as a weekend warrior, but before i bought it i test drove a GQ EFI 5.0 Auto.
I was very disappointed in how little power it had to push a GQ wagon.
5.7 or 5.8 is were you want to be for a conversion.

I'd choose a 350 chev over a cleveland every time, for a multitude of reasons.

Far more adapters are out there for the chevs, so picking them up 2nd hand at a good price is more likely. The chevs are arguably easier to mount; are narrower, which make fitting exhausts around steering etc. much easier. Lots more bits available for modifying the chevs, which again tends to make the parts cheaper.

I've worked on quite a few straight LPG V8s over the years, and for power output and economy, clevelands just aren't in the game.

The only real drawback with a chev is that, like Jags, they reckon that if it isn't leaking oil then it's got none in it.

don't most engine conversions need to be from the same year model vehicle or newer?

[coxy321]

More or less, but there's also some fine print regarding emissions, which is why some people go to a straight gas setup.

Hey gueey, i bet you're spewing you parted the ESP with the prices these days!

At the time i advertised it for 8K, it was a 1 owner , 351 4 speed, monza red, bathust globe rims all original with a stinking hot motor and i could not get one person to look at it.I ripped the motor out dropped in a good 302 runner, dropped it to 5K and i sold it! What a shame!!
If only new what a few more years would do.

The mags on my ute are off a 6 cyl XD ESP that I bought for $400 just for the mags... Sold the front seats for $600 and back seat and dash for $400.
Took the rest to the tip. Nobody wanted it..

[chunderlicious]

Good option, only dud thing is the dizzy is at the front of the block.

The Clevo can run some big numbers if needed.

have a look at where 90% of 4wd dizzys are mounted. at the front of the motor or to the side in the front half of the motor. sierras are the only motor off the top of my head that has a dizzy mounted high and at the rear. hilux have them on the side of the motor and patrols and cruisers it is right at the front... just as unprotected as a ford dizzy.

and to top that an AU falcon Windsor doesn't even have a dizzy. You could mount the coil pack in the cabin if you were that worried about it.
I'd also argue the point on parts availability, just look to US market and it's about even with the SBC.

As far as physical size goes, the SBC and windsor are close enough to the same.

i got a 302,plus full conversion kit including 5 spped and transfer for a 60 series off this site,engine mounts and all for 800,down the track will exchange 302 for a 351 clevo,i want to see how a 302 goes first,chevs are the more common swap as well as holdens,but theres plenty of ford swap options to,go the clevo

[CanberraMav]

Ive got a 351 in my 60 series.

It goes really well. Its a neat conversion using Marks adapters.

Can post a photo if you want to see how its sits etc. It has a really long extension on the bell housing

When it's time to rebuild keep the 302 rods and just get a 351 crank, ACL make pistons to suit, Longer rods= more torque.

And yeah if i EVER put a V8 in my 60 it will be a clevo for sure, 392ci AFD Alloys.
Like this minus the ram

[brad-chevlux]

i wont ever be using AFD heads again.
sure they make power, we made 1002hp with hand ported 4V AFDs.
But we have sold about 5 sets, 6 out of those 10 heads leaked water past the valve guides and one set had been machined incorrectly for the rocker studs.



I still think a clevo is waste of time. you can build a far better engine from a windsor.

Whats your personal choice for a 302W? GT40P, ported/polished/big valve stock 302W heads, something else??

[YB.LOW4]

CHI make good heads. that would be my choice

I would start with a 302w roller block 347 stroker bottom end, just a cast crank and forged I beam rods with cast pistons, off the shelf AFR 165 heads a cam to keep all the power under 5500rpm
i'd also use the explorer manifold fromt he EL or AU engine.
All running on the factory AU falcon EFI sysem with a custom tune on the factory ECU.
i wouldn't waste my time on LPG or with carbs. Drivability comes from a good tune, the ignition side of if is more important. You just can't get a good enough tune with dizzy that uses a mechanical advance.

Using AU falcon gear means no dizzy at all, so you can mount the coil pack high and dry.


Where the power is, is decided by the part you put into it.
stock SBF heads both windsor and clevo just don't cut it anymore.
Windsors are asthmatic and clevo ports are too big and have the WORST short turn bar none.

It costs to much to put EFI on a clevo, so that rules the clevo out straight away.

Cast iron clevo heads had a place on engines about 20 years ago. the ports are too big, they have a bad short turn and exhaust ports are beyond belief.

Why would you step backwards to an carby style duel plane manifold?
and then put mechanical dizzy into it?

As far as wondering goes, i'm wondering how you can compare a 60s/70s engine to any of late model roller block EFI engines?

there is a reason ford didn't put EFI on the clevo and run with that engine and it had nothing to do with ford US telling them too, our falcon engine are nothing like what they got in the mustangs. our EFI system although based on similar ECUs is not the same.


One thing i've never understood, is why people continue to use carbs/LPG with mechanical dizzys, in a 4by while off road you want good drivability and control, THE LAST thing you want is a carby and mechanical dizzy.

I'm not going to change your mind, but if i can convince at least one person not to use a carby clevo in 4by, i'd be happy
