I think you did ok. Love them or hate them if it wasn't for guys like Ron and Jim back in the day keeping FE high performance alive we may not be so lucky today to have all the great new modern parts available.  They do look alot like the pop setup and either way I think you got a very decent setup  and goodies  to go along with it for a good deal..
Good score in my book..

Myself, id get a sheet or roll of gray gasket material atleast and make a couple gaskets then use "a little" sealant.  Jmo.

I'm on the road but will be home sometime tomorrow.  I'll get you some info.

It's a very good block and ready to go. Everything has been done, however like I said it block filled and would be race only.

Man those old blown SHOC's look sweet.

I'm thinking cool factor,  since it's mostly street, a 2x4 setup on a tunnel port would look and perform awesomely. . And in a 66 galaxie! !! 2 door ?  Awesome. That was my first car ever. No tunnel port though lol, just a 390 4v.

I think the prices you offered were very fair considering they still Needed to have the work done. The after market block would for sure be your best bet if it's within you're budget  . You have little choices with the 27 stuff. Now me, I always use the smaller bore stuff so I can make about any old garden block work.
