It looks like your shaker scoop is sitting too high, you don't have an engine compartment picture so it's hard to tell what the problem is. May I suggest that you carefully remove the shaker/carburettor assembly to see what the obstruction might be. Otherwise your build is nicely done. May I suggest a little extra detail with some black paint on the mesh sections of the front grills. If you like the chrome look you could add some panel line black wash which will give it a more realistic look. Well done Grant on a very clean build.
