Definitely not a marine block, hence the hefty price tag on it. These are very, very difficult to locate and especially as nice as this is. All the hardware is there and it's freshly checked from the machine shop for cracks with a clean bill of health, he said he would run it back at standard bore. I'll throw in the $ nodular crank if wants it. This engine was running not long ago. Call me for more information.
Thanks,
Jack
