I would like to say hello as a neewbe to the forum. I bought the car as recovered from theft at an auction in the USA and brought it to Poland (a country in europe

) Currently I am trying to restore it but I am not the first owner so there is some things to improve

the car has a changed engine and transmission - factory it was a V6 and maunal transmission and now it is a v8 350 (I think) chevy with automatic transmission (probably th300). Unfortunately, due to human error during the transportation of the car to europe (more than 3 months) water poured into the engine through the carburetor and did damage mainly to the head. After replacing the carburetor with a new one, the car came to life but probably some valves are not holding pressure and the engine is not running as it should. I hope I can find help here in selecting parts for the overhaul - I know quite well about mechanics and engines, but finding and matching parts in US engines is sometimes a mystery to me
