Making my 360 into a 410

CurseOf67 · Post by **CurseOf67** » Sat Nov 07, 2009 9:17 pm

I have a 69 F250 camper special that I bought as a project truck and it has an FE 360 and C6 trans in it. I started researching what I would need to turn it into a 390. Sounds like it is pretty easy. Then I was reading about people that wished they would have spent just a little more and turned theirs into a 410 or even a 416. I do not have much experience working on vehicles and have never rebuilt an engine. With my lack of knowledge would I be getting in way over my head if I attempted to turn my 360 into a 410 or would it be possible for me to accomplish this? What kind of special equipment would I need for this project? Any advise would be appreciated. I would hate to tear the engine apart only to figure out I am in over my head.

Building 360-390-410 all take the same amont of effort just some cost more because of parts and machineing needed for what you want to build,All would be FE motors just different bores and strokes,I would suggest buying a book or manule that will tell you how to rebuild a FE and then you would know weather you feel comfortable building your motor and what tools you will need. The most important in my opinion is finding a good machine shop, because it could be the difference between a good running motor or a motor that you wasted your money on,because of bad workmanship.If you know of someone that races and builds their own motors ask them who they use and drive as far as you have to for quality work.I dont know about making a 360 into a 410 because ive heard that a 410 is a 428 block with a 390 crank but i could be wrong about this,if you have never built a motor before i would suggest you make a price list and figure everything you need and how much it cost for everything needed,It cost me $2500 for the last motor i built 2 yrs ago and it was nothing more than a built to last stock engine.when you find a machine shop you like talk to someone there and tell them what you want and they will tell you what you need before you start.

Actually, a 410 is a regular 390 block with a 428 crankshaft. Very easy to do. However, considering the expense involved (428 crankshafts aren't exactly growing on trees), I think you'd be more than happy with a 390 conversion for your truck.

Yup...

you can get a 428 crank here for $302.

You'll need the 390 rods, and you just need the 410 pistons which are also 390 "truck" pistons.

You can also buy new cast 428 cranks from SummitRacing.

There is no more effort to building a 410 than a 390, just a bit of added parts cost. You will need to either have the crank neutral balanced or use a 428 flex-plate/flywheel.

I've decided I want to turn my 360 into a 410. Spoke with John at SCAT and he said to go with this rotating assembly and to just let the retailer know what bore pistons I need. http://www.jegs.com/i/Scat/942/1-94624BI/10002/-1 Can I get some verification? Because my understanding was 390 rods whereas the kit includes 428 rods (6.490")

390,410,427 and the 428 all have the same length rods 6.490

Why not just go with a 4.25 stroke crank and get 445 cubic inches

Nice way to revive a 6 year old thread ..........search feature looks like it works good

+1 on the search feature!

So are you saying make a 427? My understanding is a 427 is a 390 crank but is bored almost a quarter inch over, and a standard 360 block won't support that kind of weight loss with that kind of compression? Also, there are the oiling differences that standard blocks don't have either.
I'm certainly open to any guidance though, I am by no means an expert. I take stuff apart and put stuff together.
Thanks

How did you get a suggestion that I said you could make a 427 out of your block

Ford also made a 427 with the same exact oiling system that your 360/390 has

If you reread my post I said put a 4.25 STROKE crank in it .....Not bore it out to 427 bore size...Which by the way no other FE block will take the 4.23 bore of the 427 other than a true 427 block and LIVE
The Fe engine family uses 2 different length rods the 352/360 take the long rod...The 390/42/406/410/428 all take the short rod ....Which has nothing to do with Cubic Inches.It does not increase or decrease the stroke.It only effects where the pin in placed in the piston ...

If you want cubic inches the best way to do it is with a stroker kit .Which will include a crank,rods and pistons and run you about 2200 dollars

I wasn't sure what engine you were referring to with 445ci so I ran with 427

Post by **Ranchero50** » Sat Oct 10, 2015 6:07 pm

Yes, long stroke needs a shorter rod or the wrist pin is up in the ring package.

Most of the 4.25 stroke FE engine packages actually use an even longer rod at 6.7 inches long

Man, a big block will make more power reliably than a strokered FE. More parts available at a cheaper cost. I have built many 352's, 390's 427's and finally a 428. Swapped out to a 460 and made more power at less RPM's and a cheaper budget. Just my opinion. If you are going to front the cost of machine work and a stroker kit, spending the same amount on a 460 will yield much more at the same cost. Abiding a different trans.

I'm not actually wanting to do any machine work I can't do with hand tools, and I can get my rotating assembly balanced from SCAT, and I don't know anything about cubic inches, I simply want to get more power and efficiency out of my 360 without spending much over $3K, now if that involves ci, then I'm all ears, just imagine I know nothing about the subject.

Based on the rotating assembly and piston combo I get 10.17-(1.660+6.490+1.99)= 0.03
[Deck height - (Compression height + Connecting rod length + Crank throw) = Deck clearance]

The Standard Cylinder Heads have a Combustion Chamber Volume of 68.1-71.1, and given the 4.05" bore with 0.03" clearance, and using a normal Fel-Pro gasket, what compression ratio am I looking at?

Going the 410 route seemed like the easiest method. Would this rotating assembly http://www.jegs.com/i/Scat/942/1-94624BI/10002/-1, these pistons http://www.summitracing.com/parts/uem-3 ... /make/ford or http://www.summitracing.com/parts/UEM-1139-STD/, factory heads, this intake mani http://www.jegs.com/i/Weiand/925/8012/10002/-1, and this Street Demon Carb http://www.jegs.com/i/Demon+Carburetion ... K/10002/-1 tied up with some shorty headers be a good start?
Thanks,
