Please check out J&M machine in Southborough Mass, not far from you. They have an amazing shop, dealing exclusively in antique automobile engines. While they have done hundreds of Model A's, the also do any other engine, from RR to the only running PT boat engine.
They welcome visitors if you want to see the shop. During my rebuild, they sent update photos to document my engine.
I did my engine done there, as well as several of my friends. PM me if you would like to stop by and see how mine runs. I have no business relationship to the company, just a happy customer.
They have a Face Book page, and a site http://jandm-machine.com/marine.html
