I am pretty sure the 360 and 390 share the same block with a 4.05 (I think) stroke. The key difference is that the 360 uses the 352 crank shaft. It was first offered as a truck motor in '68.
I am not sure why, but it seems the 360 always got a bad rap. I have had a couple of them and they always worked well for me.

Woops....make that a 4.05 bore and not stroke. My mistake. I think the stroke is right at 3.50 on the 352 crank, and 3.78 on the 390 crank.
That's correct, 4.05 bore X 3.5 stroke for the 360. The 352 had a 4.00 bore X 3.5 stroke.
I've heard the early 352 blocks did not have the same core castings, can't be bored out as far. Going to a standard core casting with a 4.05 bore probably made things pretty simple in the factory. It is said the later 352s can take the same over bore as any other 360/390.
The reason the 360 gets a bad rap is the fact that it was intended to be a truck engine; meaning low compression so it doesn't ping it's-self to death. They did come with a warranty.
I just stumbled on to this section of the list! It's pretty cool to see that you guys are still championing the old FE block Ford's. It brought back some wonderful memories.....that motor was so special...I still have it to this day. I just haven't figured out what to put it in yet.
First, welcome aboard, stop in often!
Don't worry about you FE predicament, there are plenty of guys here well qualified to help you spend you children's inheritance! LOL In all fairness they have saved me thou$and$ by not buying parts I'll never fully utilize.
One more thing: Watch out for a guy named Russ, or you'll be passing everything but the gas station. LOL
The 352 uses the same rods as the 360, a 360 is a bored out 352. Other than the bore there is no difference in design.
The 352 had a 3.5 inch stroke. Much shorter that the 3.78 of the 360/390/etc.
If you look up aftermarket con rods you'll CC lengths of 6.490 for the above engines.
Just no mention of the 332 or the 352, because the rods are different.

Thanks for the welcome Hypoid! : )
I remember going through this like it was yesterday, well sort of... : )
I had a 352 and scored a 390 crank for it. I thought it would all bolt up!
Wrong! I sourced some Rods and Pistons to complete the swap. I had the 352 rods reconditioned before I acquired the 390 rods. I remember comparing them when I got the 390 rods and noticing just how much more meat and stronger the 390 rods were. Hell this was well before the 360 came out. : ) I could be wrong on length, but there is quite a difference in weight and strength. Hell this was thirty years ago. : )
What I find great about today is the cool aftermarket stuff available. There is so much more than back in the day. Aluminum heads didn't even exist back then, Tunnel Port stuff was unobtainum! Intake manifolds were limited to choose from as well. Trickle down stuff came from the Wood Brothers or Hollman and Moody, and it cost an arm and a leg, not to mention a small child. I'm off to surf some of the sites sponsors!

well, if it is out of a grain truck then it would almost have to be an ft block, it will have a reverse 105 on the front drivers side beside the water pump on the front of the block. usually the light truck and car engines had 352 in this spot. the 105 blocks i my opinion are better blocks, you should then have t codes all over the motor. the heads should have a casting code of like say, C6TE-G or D2TE-AA or something like that. intake should then be the same way.
Thread Bump....Your username is interesting. Have you built a 390 to CobraJet specs? What would that entail? I would like to do something like that to my '68 F-250 Camper Special if it is within reason on cost.
It can be done with a standard 390 block and rods with 428 crank, 410 pistons or other aftermarket set, early large port heads w/2.09-1.65 valves, large runner intake and a cam to match intended use. This will be a 410 build when done that will run quite well. This is what i'm running the last 19 years in the 68 CS but have 13/32" rod bolts, CJ cam, internal balanced, a great torque motor with fuel mileage, well not the best or worse.
