340 block with NO main caps
When I was buying and selling early Hemis I bought a '56 354 that had been buried in a manure pile in the 50's in an old barn in southern Wisconsin.
The guy told me his Dad wrecked his 300C a few months after he bought it...loved the motor so he kept it.
When I got it the manure was a nice pile if black dirt with that Hemi sticking out the top.
Yes I fixed it.
