I started my 68 f100 crown vic project a while ago and I am now at the engine decision part.
I got the new crown vic front end in. I still need to drop it a couple inches. Also got the rear end done.
The donor crown vic came with the 4.6L and trans, not sure if they are good. I still have the 360 and 4 sp manual trans that was in it, but they need to be rebuilt.
If I go the 4.6L route, I would need to purchase I think around $2,500 for new wiring harness, re-program computer,etc. On the other hand the 360 engine rebuild would probably cost around that much.
Any thoughts on any other good engine / trans combo that is straight forward and well documented? I would like this to be a daily driver.
Ive done a few restos, but never really done an engine swap.
I am not all that familiar with the ins and outs of the transmissions. Is there a popular engine/trans/software setup that is commonly used in projects like this?
I have seen people use Chevy LS engines in every thing under the sun, but I wanted to stay Ford if it is not too much of a hassle.
The manual transmissions in these trucks are not for jamming through the gears if you care about that. So affordable swaps are 302, 351w, or a 460 with a c6 if performance is wanted.
The 360 can be brought to life also and there where 3 speed autos bolted behind them.
If you care about overdrive I would go with the 4.6.
I am sure others will chime in with advice as well.
Your best shot would be a ex Police package. The computer does not have the passive anti theft. The main thing is to get the engine harness and harness that goes to the computer. If you get a wiring diagram and study it you will see that connecting your truck to the engine is not that hard. There are several companies that make a plug and play for the 4.6 engines. Also the large Ford vans and F series have the 5.4 that connect the same way.
The Lincoln front wheel drive SUVs also came with a 32 valve 4.6 that had a front sump pan. You could rig up one of those with a T45 if you want to stay with a standard transmission.
Of course you can also go the Coyote route from a Mustang or an F series truck. Those are even easier to get after market wiring and computer controls.
So the 4.6 I have did come out of a police interceptor. Unfortunately, most of the existing wiring harness did not make it. I have a 4.6L block and the auto trans that came out of a 2007 Crown Vic.
As you were saying about the availability of different aftermarket wiring harnesses available I am leaning toward the 5.4 at the moment. The wiring and computer seems much easier on the 5.4.
Stay clear of the Triton 5.4, my opinion. I'm a die hard Ford guy, but after replacing the 5.4 3V in our 2008 Expedition at only 98,000 miles, I'll never own another one.
The only advice I can provide is the wiring harness for the 4.6. I got mine from Ron Francis with a tuner to eliminate the PATS system for about $1500. It was more money than thinning a factory harness but so easy to install. Every thing came in bags and was labeled, each wire was labeled as to where it goes and step by step instructions.
You can run the crown vic gear a lot cheaper than $2500. If you are handy at wiring you can swap the whole vic harness and zip tie a pats key to the sensor. It'll be a lot peppier than a 360.
I though about it and researched it but ultimately decided to stick with my 460 build.
Wow! I had no idea the carb intake was available. That does look awesome!
I will stick with the 4.6 I got from the cop car and hope it runs. Its not locked up so there is promise.
I am definitely after the overdrive. A daily driver that does not suck the gas of the 360 is worth the switch.
In efforts to get it running quicker, I will keep saving the nickels and eventually get the Ron Francis product(s). I still have plenty of other things I can work on before I need to put the wiring in. When I stripped out the cop car, I had a short amount of time to get the parts out of it before it was hauled to the junk yard. I kept the computer and all electronic components and then cut all the wiring harness about a foot before each terminal end. So I think I have all the correct plugs in case I really got ambitious and wanted to roll my own harness, but obviously it would never look as good as new.
