If it's just a run of the mill 390, in non-running condition I wouldn't offer much more than $200 (confirm it's an actual 390 first).

You can measure the stroke 3.50" = 360... 3.78" = 390

Or, if the engine is apart look at the casting numbers on the crank 2T, 2TA = 360... 2U, 2UA, 3U = 390

the only numbers I could find were cast into the front of the block. 352 78. the bore was 4.05 and stroke was 4.7. it came from a 67 galaxy. he was unable to locate the heads or intake. I already have the 71 360 in my truck. combining the crank and rods from this engine into my 360 will make it a 390 right?
