just going through the car for now. i would like to get it running and stopping but it could be a long road. its been sitting for ten years now. i have most of the parts for the car. there was a O ringed block but that was lost a few years ago. today I went and picked up a new long block but we were not safe with the forklift

I guess now i have to tear it down

well its not blown but here are some dgv's on a cast dual manifold
