Not sure yet. I was thinking about building a 20's looking boat tail speedster for the street. Side draft Webers or SU's, T5 trans, finned aluminium drums, dropped solid front axle, etc. I have a 53 two door post special that runs pretty well and I acquired this spare engine a few years ago. Its just been sitting around and I need a project.I am not sure just what the sizes are. I had a local performance engine machine shop do the head. I asked for as large as he thought would work. Only a sixteenth or so between valves, No on stainless. Narrow angle seat grind, . Ports can't be cleaned much, but he did what he could.
What do you plan to do with the engine?
