Good price on a 4 liter?

[seth247]

So I just left the salvage and he's got a running 4.0 out of a first gen and he wants 300$ which sounds like a god deal to me.
I'm planing a full build with new headscampistons and all that.

What do you guys think?


Also while inwas there I was looking at a 5.0 out of a crown vic(wants450$) and I realized he intake manifold was pointing the WRONG way towards the driverside.

Is that just some thin they did for the crown vice or what cause all the mustangs ive seen point towards the passenger side.

Thanks guys.

There are a few 4.0's for sale on here -- check the For Sale section.

Since your going to build one.. Look for a member here with a spare that they are willing to part with cheap/free

I bought one for $150 and got another one for free.. Expect the heads to be cracked but thats normal.. They can normally be repaired...

I gave one away to a scrap yard (as payment for them taking a non titled vehicle off my property).. the other I'm keeping as a spare short block (just in case).

edit: I just remembered, my Neighbor has a pair of explorers (1991's).. a 2wd manaul trans with a blown motor and a 4x4 auto with a good motor (front suspension damage).. He wants $500 for the pair.. You should be able to find something like that out there.. especially since your going to do a rebuild anyway..

yeah I'd love to support another member of the site but I couldnt find anything in the tulsa area in the for sale thread and I spend too much out of state already. Need the feed the local economy.

Any way what do you think about the price and any info on the 5.0 motor I'm curious about that.

 

[Maniak]

$300 is a good yard price for a "known" running motor... If its not known good then its not a good price.. but not extremely bad either..

As for the 5.0, I can't answer that..

 

[seth247]

Thanks maniac
yeah its a known running motor
and if a get it here I can have someone to yell at if somethin ain't right(even if it doesn't got me anywhere I can still threaten to open up a drumawhoopass)

The intake is turned around on the crown vic due to, I believe, room under the hood for the intake routing. Mustangs have the filter box on the passenger side. Crown vics, t-birds, and maybe some others have the filter box on the drivers side.

Thats interesting, so can you just flip the manifold around on a 5.0 or did they acually change the design to make it fit the other way. Might be usefull.

Section I regularrly pay $300-450 around here in Denver to the yards for OHV 4.0L's. however I avoid first gen blocks if I can because you can find later model Ranger and Explorer 4.0L's with less miles for the same price... 98, 99, 2000, the blocks are all the same and will fit any year OHV truck with some work (take it down to the long block then bolt on all the proper year intakes, fuel rail, sensors, flywheel, etc)

 

[Maniak]

I thought some of the newer 4.0 ohv blocks used a different flywheel/flexplate (more bolts)?
If that is the case you could end up needing a new flexplate/flywheel if you got a really new long block..

~Mark

 

[410Fortune]

Yes you could end up buying a flywheel or flex plate from Ford if you get a later model OHV that was used with the wrong transmission.

I have done this both ways, I have put a 99 5 speed engine into a 95 auto truck, I just put a 96 ranger auto engine into a 94 sport 5 speed, both times I had to swap to the 8 bolt flywheel.

I bought a 8 bolt flexplate from Ford for $40 with bolts
I then had the flywheel laying around for the next project, 96 ranger into a 94

So now I have one more 8 bolt flexplate

My point is this is not an expensive part
AND if your truck is an auto and you buy a 8 bolt 4.0L from an auto you dont have to swap anything... the flexplate or flywheel is identical to the earlier 5 bolt cranks in every other way.

The cam position sensors also all work together, some just require some simple wiring.

I cover all this stuff in my threads, the 97 into a 95 thread is around here somewhere..
The OHV changed VERY little from 89 - 2001 IMO, just the intakes and fuel systems

I believe Ford went to the 8 bolt crank in the OHV because thats what the SOHC's used and they all share the same transmissions...so one flywheel/flexplate fits both V6's

 

[Maniak]

Gotcha..

so.. if you stay with a long block (don't try to mix old head and a new block or vise versa) the worst you would have to do is change the flywheel/flexplate which is a cheap part.. That is other than chaning sensors or adding block off plates (i.e. no cam sensor on < '93)

[seth247]

when you say 8bolt are you talking about where
it bolts to the crankshaft?

 

[Convict1997]

I know I'm late, but yeah, you can just flip the 5.0 manifold around. The mating surfaces between the upper and lower are symetrical. No other modications to the manifold are needed. Depending on the vehicle, you'll need to figure out the wiring, coolant lines, and intake hose routing, though. This is only for the regular 5.0 intake though. The intake runners are in a straight line front to back. The GT40p intake on the explorers has offset runners and I don't know if the intake can be flipped.

 

[seth247]

is the gt40p the one that has "cobra" on it?

 

[Convict1997]

Unless someone changed out the top plate, the GT40p shouldn't have a cobra on it since the GT40p came on the explorers. I've been out of the 5.0 scene for awhile but, if I remember correctly, there are three versions of the intake. The original GT40, The GT40p (explorer intake), and the Cobra. There was a comparison done between the three and the hp/torque numbers were very close. The big difference was in the price. Obviously, the cobra intake off a mustang will be the one with the cobra on it. Click here for a link to information on the GT40 intakes.

 

[WickedWindsor]

The only 5.0 (upper)intake manifold you CAN'T do a 180 with is a truck upper (F150). All others including the GT40/Mustang/Thunderbird/CrownVic CAN.

Do NOT get a Crown Vic engine unless you plan to strip it and rebuild it from the ground up. It had narrower intake runners and a smaller throttle body than even the stock mustang, 55mm I believe as opposed to 60mm (stock Mustang). The EFI system is also speed density as well.
Save yourself a lot of pain now!

 

[seth247]

yeah I for SURE don't want speed density!

I usually pay $350-450 for an OHV 4.0L with 90 day warranty from the local yards. Years range from 96-2001, I try not to get the 91-94's definatley not the 95, but it depends on miles. With around 100K miles with most accessories (they steal the alternator and AC compressor) I would say $300 is more then fair assuming they tested it before they pulled it, the oil looks good, the compression is good, and most of all, you trust the people selling it.

I have done many 4.0L transplants into trucks with cracked heads, etc, $300 is on the low side for a good 4.0L OHV
