hey guys I just got a 70s 429 thunder jet I was considering putting it in my 92 f150 4x4 with 5speed. Would i be able to use my tray and such? Would this be a good engine alternative? my 5.0 is all but dead. Thoughts?

 

One thing you will have to check on is smog control. As you are going into a 90's truck, you may have to make sure that the 429 will be brought up to the 92 level of emissions. Also, I doubt that the 5 speed will be able to handle the HP and torque of the 429. Same for the transfer case.

 

Thats a doable swap. Not that much to it if you have a large displacement Transmission/bellhousing.

 

The 5 speed M5OD cannot handle the torque of a 429. You would have to do a ZF conversion or throw an automatic in it.

 

Just did some searching around. As an example, it is illegal to swap an older engine into a newer vehicle in Colorado. You will have to check the laws in your state. In other states I saw examples of the engine has to pass the emissions of the vehicle year. Others state no none fuel injected engines can be used if the original was fuel injected.
As a start you might try this google (swapping older engine into newer vehicle "emissions laws"), without the parentheses.

 

It would be possible to add fuel injection. I think 460 stuff could swap onto it..

 

It all depends, like I found, some states make it illegal to put in an older engine, period. Does not matter whether fuel injected or not. It all depends upon which state he lives in and what the laws are. If his state does allow it, he may not be able to license it in another state if he moves.

 

Here in Utah it comes down to the particular county. Some counties dont have emissions at all some do. If you live in a rural area your pretty safe.

 

I believe you are talking about testing. That would be totally different than what you can do as far as an engine swap. That would come under state and federal DOT.

Edit - Did some more searching and found this. It is not gospel, but the person states he contacted Utah Govt about the emissions. Per them, the same or newer rule on engine swaps is federal.

Have not been able to verify. There will always be exceptions, kit cars, cars older than xxxx, etc.

 

For the OP, why not look for a freshly rebuilt 302 or 351 from 92 up?

 

kingfish, not everyone cares what legal...



BUT they'll be the first ones to complain if busted

 

Especially if they decide to sell it and find out they can't. Or move and find they can't license it.

Like I said, I would go with a good rebuilt 302 or 251 of the same year. Then all you have to do is swap it. No trying to figure out changes in trannie, transfer case, computer, etc.

 

Thanks for all the good feed back. Anybody know where to get an ACTUAL rebuilt 5.0 in the NW for reasonable prices

 

You might check with Ford, probably not that cheap and maybe not available that old, but I believe they are warrantying them 2 years unlimited mileage.

Try googling (remanufactured Ford 5.0 f150).

Found this right away.

Also there may be a good local shop that could rebuild your engine.

 

Thank for all the input guys. I am going to rebuild my 302. any suggestions that don't require computer work?
