Nice find. Actually awesome. Sounds like it didn't cost you a dime but your time. Better yet to boot. Stash it away and see what happens in the future. You might need it, might not. Get tired of looking at it, sell it, make a few bucks, and give someone else the opportunity to use it. I wouldn't throw out my freshly built 216 by any means, well unless it bit the dust and i had that motor sitting there. I ran my leaky, smoky, 216 for years. Only changed it because the clutch failed, 2 gear was noisy and it had to come apart anyhow. I had 261 waiting in the corner along with another trans and rearend. And glad i did. You wont have to feed that 270, so it wont cost anything, but space, to sit there either.
