Under the hood, it takes up as much room as a normal booster / master would. http://www.bunchobikes.com/1952suburban4.htm Second picture from bottom. I got mine from CPP. I have no opinion on chrome versus non-chrome. There is enough room under the hood of these old trucks that you can stack 2 14-71 blowers and still close the hood. What else did you need to fit under there?
