FE Motors
I have a 1974 Ford F-250 Ranger XLT 4x4 with a 390 motor. I was taking apart my 390 and getting ready to take it in to get machined when I found a crack in the cylinder wall. I want to keep the 390 but those are hard to come by. Can I take a 352 or 360 bare block and put the 390 internals with little modification?

The rotating assy is the same. Only thing I'm curious about though is if that motor has been changed before? I'm pretty sure Ford wasn't putting 390s in the 74s. Check the stroke it might be a 360. Its the only way to differ the 360 and 390. I'm just looking out for you before you start buying 390 stuff that won't be right. Most people convert there 360s to 390s. Look into the FE forums. They're the Gurus, I'm there a lot for my own.

The Motor in the truck orginally had a 360 in it, but has been changed, I measured the stroke of the motor and it was 3.78" which is a 390 and the block is painted green which I have been told is a remanufactured block

Your 390 can't talk cause it hoarse ?
The Horsepower/Torque specs can normally be found in the FE engine forum
360 = FE engine
360
The 360 (of 360.7 in³ or 5.91 L displacement) was used in the F Series trucks and pickups. It is basically a destroked 390 with a bore of 4.05 in (103 mm) by 3.5 in (89 mm) stroke. The 360s were known for having sluggish performance because of the truck camshaft, mostly noticed by F100-F350s. Use of a standard 352/390 cam for use in passenger cars along with carburetor and distributor adjustment gave it the same kind of performance as the 352/390 car engines. First introduced in 1968 and phased out at the end of the 1976 year run. Rated at 215 hp (160 kW) at 3600 rpm (2-barrel carb, 1968).

This may help.
CI bore stroke
332 = 4.00" X 3.30"
352 = 4.00" X 3.50"
360 = 4.05" X 3.50"
390 = 4.05" X 3.784"
406 = 4.13" X 3.784"
410 = 4.05" X 3.984"
427 = 4.23" X 3.784"
428 = 4.13" X 3.984"

You can also have the cyl sleeved. Runs about $100 a hole here. Might be a easy alternative if you have no other blocks close by to pick from. Even with a good used block you'd need to mag and pressure test it. Then whatever machine work it needs. Also the cost of the block too. If you do the sleeve just find a GOOD shop that can handle it. If the rest of the block is nice and it's not been bored to death it's something to thnik about.
