Here is my clogged chevy 305 intake . The engine is 20 years old and was probably never open. I was not able to go at high speed , but the engine was starting and running fine . I don't know for sure, but it has something like 300,000 to 400,000 km and still going! Anyone ever seen something like this??? Since a lot cruisers runs with chevy engines, I thought you might be interested in this....
