Nope.
Based on reports from others in these forums, 440275 indicates a 352. As noted previously in this thread by
HH56, a 374 would have a casting number of 440971.
Plain valve covers were 55 Clipper only, but used on both 320 and 352 engines (together with a Clipper decal).
However, the description for that air cleaner sounds like what was fitted to 56 Clipper Custom and Executive models with the 352 (and Carter 4-bbl. carb).
