Alright, I'm back. Need more advice.

I know the 89-93 mustang/mark vii is the engine I want, but I am low on cash and something has tempted me. I can get a mark vii w/ comp, wiring harness and engine for $750, but I can get a crown vic engine, wiring harness and comp for $200 at the p-n-p.

How bad is the crown vic compared to the mark? Is it worth $550?

Alright, another question, how is the truck 5.0 compare to the crown vic?

If I do get the crown vic or mark, should I get an F-150 flywheel for the 5.0L? because I don't know how to get a larger one balanced for the 5.0L without having one for the 5.0L.

Would I just be better off trying to find a truck 5.0L? I am sure I can get these fairly cheap compared to the mark also.

This is being bolted to my NP435.

If you get a car 5.0, you'll still need to find the truck flywheel, bellhousing, clutch, and starter anyway. If you can get a truck 302 flywheel then it'll already be balanced right, so no worries. It's only if the flywheel you get is older (pre-85?) or from a 300 engine that you'll need to have it rebalanced for 50oz. A competent balancing shop should know where to put the imbalance, and how much.

Don't know nuthin' about the power levels of the Mark vs truck vs Crown Vic, sorry. I was lucky enough to find a Mustang engine.

I have a mustang 5.0 in my 89 Ranger, but my friend has a 5.0 out of a pick up (early 90's) in his 88 Bronco II. The power want be the same, the mustang has more horses, plus a lot greater aftermarket support. The problem he ran into was the intake sive. It stands to tall. He couldn't put his hood on until he got the mustang style intake. I think there were other minor problems but I don't remember them. I would spend the money on the better motor. It isn't a good thing to skimp on and then be unsatisfied. I have heard my friend say how mine went in easier and was a better fit, but he got a really good deal on the motor.

First off there is a reason they say get the 89-93 motor...... PERSONALLY I have a 91 Stang motor and that is what I would recommend anyone else to get. Mustangs 5.0 has a Different Fireing order than other 302..... which is the same as the 351. Now the 5.0 since in 83 they have a 50 oz imabalance wehit which is when ford "changed" the name of the 302 to 5.0. you dont want an 86 stang cuz the heads SUC...... also if you get a 89-93 you can get the aftermaket harness or use the stock one and it's like 10 wires and it is hooked up. The Crown vic has the MOST restrictive air inake along with 14 lb injectors and NEVER cam with a MAF..... the Mark motors are the same as teh stang but they never came with a MAF as far as i've been told. when getting your truck flywheel make sure it is a 302 not 351... and if you get a stick 5.0 out of a stang you can use that flywheel just have to get a car bell housing but the truck is more preferable becuse of the increased clutch size but has the draw back of the bigger bell which causes clearance issues. As for me I found a complete 5.0 stang for $600 and i found Complete crown Vic for $200.......... It was worth the differance to me.......


Sitton High..... hey man I live in auburn too..... drop me an email if you wanna hook up and hit a hole or just chill?

and if you get a stick 5.0 out of a stang you can use that flywheel just have to get a car bell housing but the truck is more preferable becuse of the increased clutch size

The car bellhousing won't bolt up to the NP435. Bolt pattern is wrong (though the bosses are there for it), and the hole for the input bearing retainer is too big to fit the 435 as well, so it'll be a bitch to align properly. Oh, and the depth is wrong too, so the 435's input shaft won't poke into the pilot bearing.

You really do need the truck clutch, flywheel, and bellhousing. Besides, the 'stang cable clutch is a pain to keep adjusted properly.

THe bottom ends are the same. SO if you get the Vic motor you can always buy a set of mustang heads, intakes (Throttel body and EGR spacer), computer and wiring harness later.

Well, today I found an 87 Lincoln Mark VII and it is a 5.0, but I am still unsure if it is HO or not. I don't think so, but I have to check the head casting and manuf date. The first half was non and the second began the HO. From what I have found on the internet all the Mark's were speed density, in 87 either way it was roller cam, and the wiring will be difficult because there are even sensors for the airbag suspension. The guy gave me the whole running car for $200 if I get it out of his yard by this weekend. I couldn't turn that down whether it was HO or not. The figures are close, non-HO has about 150-200hp (depending on model) and 275 ft-lb and teh HO is 225hp and 300 ft-lb.
I would rather have the HO, but the 25 ft-lb isn't a big difference in my eyes, especially since I am upgrading from the ol 258 with the crappy 2bbl Carter BBD.
I don't mean to disappoint those that pushed for the HO and it wasn't that I didn't listen to you or disregarded your statement it simply came down to money. I will start the swap this weekend. Thanks for all of your help and time,
Jason
If anybody needs or wants any of the parts that I don't use let me know and you can have 'em.

Jason, Nice score. Check out this web page http://cjford.stormloader.com/Jeep/jeep1.htm
C_J_Ford is using a complete car, might give you some ideas on what to sell.
If you have the time I would pop of the heads and take a look at the cylender walls. Look for the factory hash marks at 40 degree angles, if the engine has this your good. If not get someone to look at it who knows rebuilt several engines. Make sure you use the Ford gaskets, they will save you money in the long run. Start searching on options for the 5.0 like adding a G3 alternator or going Saginaw steering. Not that you'll do it right away but...

Now, get some pics of the engine, intakes at the throttle body area and stuff.

Thanks Mr. N.

Next question, I got a 302 flywheel and the guy at the yard says it came out of an 89 F-150 w/ a 302, but he was only 99% sure. So, I asked the Ford dealer to run the casting numbers to see what it was from or if it cross referenced with anything. Nothing popped up. Then I had him look up the 81-87 and 88-95 flywheels that are different listings, but they were the same part number. So, I am guessing that this is the right one as long as it came out of a 302, BUT how can I verify this? Ford had no idea and there is a Ford casted on it so I definitely know it is a Ford.
I know if it is wrong it will shake like hell, but I would rather know before hand.

I am going to ask this in the General 4x4 forum just in case there are more Ford gurus that don't check the Ford forum often.
