Back in the day I was a dedicated Ford guy.
I accumulated many Ford parts,a few I still hang onto thinking somebody might want them.

My primary concern is a Boss 351 Cleveland bare block that was a spare engine I used in my 72 DeTomaso Pantera.I actually can't remember if this is the original block or the spare. I ran both engines.
This engine block is blueprinted and bored .30 over. It has been in my garage for years and shows rust in the cylinders.

Is this block relevant today or is it worth only the value of the steel?

Thinking a Cleveland of that timeframe would be sought after.

It would only be worth the value of the steel if you had a rod sticking out the side.

It's definitely worth something to somebody. People still build/rebuild Fords for old muscle cars.

Somebody wants it, the hard part is finding that person.

As best as I can tell, the only difference between "regular" 351C and "Boss" engines are 4-bolt main bearings and cylinder heads. Having said that, these engines haven't been made for 50 years and surely a good 4-bolt main block is going to be worth something to the right collector/restorer. The cylinder wall rust, if bad enough to cause pitting, is going to hurt. Even if only surface rust, the cylinders would have to be re-honed. For now, just keep it from getting worse. You should be able to find approximate values and advertising venues in the collector magazines, e.g., Hemmings Motor News.

A 351 block has some value. New Ford performance eones from Jegs etc are over $k
Somebody building a vintage ride would want it. I’d hit up the local Ford clubs and online forums. Shipping it is a cost killer so it’s gotta be someone within a few hundred mile radius

Still have the pantera ? Post some pics.

I’d look at Hemmings for a reference. Lots of people wanting date correct parts

I would say a BOSS 351 block is worth money to someone (especially if it has an original BOSS 351 VIN stamped on it). I have seen a .30 over block listed for $600 plus shipping.

I don't know a lot about the Pantera parts identification. You indicate you are not sure if it was the original block or a spare. Do you think the block may have come out of an original BOSS 351, or is a service block?

If it was associated to an original BOSS 351 the VIN is stamped on the block left side below the head. I don't know if a Pantera VIN was stamped in a block like they did on the BOSS.

Block casting should be D0AE-L (Four Bolt) with a date code in the range of the car. Casting and date codes are right side behind the starter motor.

If a car is still alive but has a different block in them, people are always looking for the cars "original" VIN stamped block.

Its been many years since I owned the car.
I'm pretty sure the car was sold with the original engine.
There was nothing wrong with the original BOSS engine. A good friend back then, worked at a engine builder (Motor Sports Research)At that time they were the premier engine builder in the Chicago area,primarily working on Chevy engines. They eventually went into boats and Nascar and moved down south.
My buddy that worked there called me one day and said he had a BOSS 351 engine that a racer was trying to sell because he was moving to another race class.The engine was .30 over with all the best parts.
I was young and naive then and wanted a real race engine in the car.In hind sight the engine was definitely NOT set up for street use. The compression ration was 12.5-1, the cam was way over spec for a street car, but the worse was the piston to wall clearance, it was purposely set loose so the forged pistons would swell from heat and help seal the cylinders.
On the street the engine never got hot enough,long enough, so lots of smoke.
I had the original engine bored.30 over and transferred the parts to the original block, except the cam. I should have picked new pistons too because they suffered from the same fate as the other engine. Low compression engines were taking over, pump gas was not what it had been.

At the time I also had a 66 Shelby GT350. I had it torn apart in the same garage. I had the original Cobra 289 engine that had been blueprinted and heavily modified.
I purchased a spare Trans Am BOSS 302 race engine to put in the Shelby in place of the 289. I accumulated the parts to do the engine swap but never got around to finishing the project. I had Cobra 289,BOSS 302, and 2 351 BOSS engines and the parts for them scattered around the garage. I sold the Shelby with both engines and a spare 4 spd. trans, I sold the Pantera with the installed engine and kept the additional parts, eventually selling everything except the BOSS 351 block.
OMG, with the headers feeding the tiny mufflers and the solid lifter cam loping, the sound that the Pantera made was unbelievable.

From the Shelby I still have a big box of Holley Carbs that found there way to the 289.The 289 had a very rare, Shelby duel quad staggered intake manifold.I was constantly switching 2 carbs at a time to try and find the right combo.
The original 289 Shelby engine came with a special center pivot float carb designed for road racing, I suspect that that carb might have some value to somebody trying to restore a 66 Shelby.
