I was planning on adding polished cobra valve covers and matching oval air cleaner to the 289 w/windsor heads in my '70 fb but have concerns that the air cleaner will look too big relative to the size of the engine. The air cleaner measures 21" long, that's longer than the engine I think. Anybody using one of these on a small block that can persuade me that it doesn't look too big? Love to see some pics.
