I was just wondering if anybody out there could tell me what it would take to swap a 302 into my 66 F-100 for the old 352.

 

First of all, welcome to FTE. You will find a great bunch of guys and a lot of good information.

To address your question, though, to replace the 352 with a non-FE engine will be a chore. You will need to replace all engine components and most, if not all of the entire drivetrain. Nothing interchanges with the 352. Do a search on this subject, and you will find good info on other's attempts to do it.

Your best option would be to find a '68 to '78 F-100 or F-150 parts truck which has the 302 and the options you want. All of the drivetrain parts will interchange with your '66, so you can transplant them into your truck. If you have the entire truck as well, you can do the desirable modifications such as power steering and front disc brakes, using the parts from your donor truck.

Do searches on those subjects and you will find more details.

Finally, why get rid of the 352? It is of the FE family if engines. It is a good solid engine, and Ford trucks used it and/or it's siblings up to '76. The similar engines which will bolt right in are the 360 and 390. (Other FEs include the 406, 410, 427 and 428. All of them will bolt up, but they are more performance oriented engines.)

Search the FE forum here at FTE as well.

Also, search for user names: FordBoyPete, jowilker, banjopicker66 (me), and
these will give you a LOT of results on the swaps.

Good luck, and again, welcome to FTE!

 

As a matter of fact, there is an active thread on this very subject on the '67 - '72 forum.

 

gurns29,
I have a 66 shortbed with a 302 3 spd if you want dimensions or images but I didn't do this particular swap myself. Let me know if you need that kind of info.

Is it that you already have the 302 setup and this is the most economical solution?

 

Thanks for all of the information that you provided me with banjo. The 352 is shot and I could get my hands on a cheap 302 is the reason that I was thinking about going that route and because gas is going so high. Raleigh if you could give me some images that would be great. Thanks for all your help. Mike

 

The cost to rebuild the 352, or replace it with a remaned 390 will probably be the same or less as you will spend to swap in the 302 and all it's components. Also consider this... with what that 302 will take to get your brick moving, it will cost as much in gas.

just my $.02, --Mike G

 

Mike has made a very valid point. You will spend white a bit to get a different engine to bolt up, with a working transmission and all the other parts.
You will probably end up cheaper to get the 352 rebuilt, or replaced with a good 360 or 390 from a boneyard.

 

Thanks BP , I may actually be getting the hang of this...

 

Let's not forget, that little 302 is going to have to work harder than any FE engine to do the same job. I doubt your gas mileage will improve any. I get about 15mpg with my 352 with the 2v and 3 speed.

 

I hear what you guys are saying. The only problem that I am running into is finding a FE engine that runs. I live in northeast colorado and I have called all the junkyards and none of them have what i have been looking for. If anybody can help that would be great.

 

Hi gurns29, I might have a line on a FE engine out of a car. My brother is parting out a few Galixies and he might sell an engine. If you are interested I will find out for sure.

Just another twist, if you want to upgrade to power steering and disc brakes.....
you have more options.

When you say the 352 is shot, what do you mean? You would really do better with overhaulin the big block and the torque is mean. I would go 300 6 cylinder before 302, just my 2 cents though. 300 is cheaper, easier to swap. Did someone already quote you a price on machining the 352?

 

I have not got a quote on how much it would cost to rebuild the 352, but I was thinking it would be around 2,000 to 2,500 to do the overhaul. Mac if you could talk to your brother for me that would be great. Thanks for the help.

You can turn you 352 into a 390 quite easily. The only additional parts for a rebuild which you will need are a 390 crankshaft, and 8 390 rods. You will need new pistons, rings and bearings anyway, so get 8 standard bore 390 pistons as well. ( I have a 390 crank with rods if you are interested.)

Have a machine shop bore the 352 block out to stock 390 specs and install the 390 crank and 390 rods into your "new" 390 block.

(If you don't want to, or cannot afford a 390 crankshaft and rods, you have another option. Use new standard bore 390 pistons on your existing crankshaft and rods, and you will have a 360 engine.)

Have the same shop do the heads, and install them onto the motor yourself. You can proably do this all for less than $1000. Autozone and Advance Auto quited me $1200 (plus core) for a rebuilt 390.
