I put many a car motor in a truck.
Best place to find a true 390 is in a car. Best place to find a true 360 is in a half ton truck

Define "truck". In the late 60's and all thru the 70's a real truck engine (F600 and larger) were 330-361-391 sizes. In a car or pickup 352-360-390. A real 'truck" engine has a steel crankshaft, steel timing chain/sprockets, forged pistons, sodium filled exhaust valves and the whole front of the engine has a longer and different look to it to be able to power air compressors, larger alternators, etc, etc.

Ford had a thing about not making things easy to mix and match drive trains. Wink Not saying you cannot do it Confused just takes more thinking.

The neighbor down the road with a automotive machine shop, would tell you get a Chevy. As most different combinations just bolt up. But when some big spender that wanted a race boat or Baha off road engine and was a Ford guy he could find the combinations that worked.  

Wink An just for Shameless he always drove a Chevy truck that he had built from parts. The first new truck ever and he bought a FORD.LOL

When I get the engine out of the truck, I'll have to do some crankshaft measuring and see what size the crank is and see if I can find a 390 crank to match. If not, I'll probably just keep my 352 crank and turn it into a 360. 
But if I can get the engine unstuck and running well in chassis, I may not pull it. Just going to be a tooling around the farm and surrounding area pickup for the most part. But we'll see what happens. A couple days ago I got a different set of slightly later 16" rims and tires to at least get the chassis rolling and off the ground enough that I can work under it. It had the factory 16" split rims on front and 16.5" rims on the rear.

Another update: sourced a 390 crank, freshly ground to .030 under on the rods and .020 on the mains, complete with bearings and reconditioned rods for $750 plus a little for the ride. Is this a decent deal for a crank that seems to be kinda hard to come by?
Thanks

Did a quick look in the Jegs catalog. You're probably in the ballpark with crank and bearings

When it comes to parts for machines that are fast obsolescing, it all boils down to how much and how long one will pay the prices for pieces they feel are necessary to prolong the life of a machine or hobby.
