New member from Europe -some questions

Hello,
I am 30 years Old, live in Europe, Lithuania. My passion - old American cars which are very rare here. I own 2 - 1975 Eldorado Convertible, and 1979 Caprice wagon. And also as a present to Caprice, I got an old ford engine with transmission, which guy told to be from 1972 thunderbird 460 (oh I alreadu talking inch size no metric - COOL). I never heard this engine started, and I want to start it. At first I like to know more how to identify what exact engine I have. Valve covers has 7bolts. So its big block? How to identify model year? It has so called "air/smog pump". First problem I faced was distributor cap. Its cracked, and i ordered 1972 thunderbirds shown in www.rockautoparts.com and was disapointed. Arived Cap was taller, smaller in diameter and had "female conections" for wires. Mine is wider, lower and with males conections according catalogs such goes to newer fords. While looking at such items in ebay I found info, what also where are diferent caps with round vent hole an oval. So now I am confused a lot on that to order - no chances to return parts and also shiping costs are high.
Maybe you can advice on part numbers, and good sources?
Now about strting that engine - what would you advice to do before any atempt? It was not started for 3-5years. and how to deal with transmission? if it is left it will leak at rear seal - shaft removed ( i have it).
How to identify transmission lever position - is park in front or rear posistion?
Thanks a lot for all ideas

You can determine the exact year only sometimes by referencing the casting number cast into the heads; unless they have been changed at sometime.

But no engine casting numbers yet. Where are they located?
So any ideas, on what exact engine it is, what ignition and etc are very welcome.

Labas,

From which part in Lithuania are you coming?
