I have a bone stock one in my GSR DA, just trying to get an idea as too what its worth.

 

whatever someone's willing to pay for it

 

I just know there extremely rare, I cant find a price on one anywhere

 

 

They're rare, but not particularly valuable. They make the same HP as a B16A with a little more torque from the extra displacement. Like others have said it's worth what someone is willing to pay for it.

 

Boeing B-17 Flying Fortress is a four-engine bomber airplane difficult to remove, then in 1930 against the United States Army Air Corps (USAAC). Competing Douglas and Martin the contract to build 200 bombers, the Boeing entry passed by both the competitors meet the Air Corps' expectations. Although Boeing lost the contract because the prototype crashed, the Air Corps was so impressed with the Boeing design that they ordered 13 more B-17 has a more detailed assessment. Its introduction in 1938, B-17 Flying Fortress developed many of the design development....

 

I would say between the price of an obd1 B16 and an obd1 Gsr motor, so...... between $1200-$2000, They are rare, but there is nothing particularly special about them, except they are harder to find parts for than a b16 or Gsr motor...

 

Id say on par with a B16 and really depends on condition you kept it in and how much someone is willing to pay for it.
